Opinion by Judge TROTT; Partial Concurrence and Partial Dissent by Judge REINHARDT.

Scott Schwartz was a young man who walked with the aid of a leg brace and crutches. Shortly before midnight on January 24, 1980, he picked up hitchhikers Dar-riek Gerlaugh, Joseph Encinas, and James Matthew Leisure. What Mr. Schwartz did not know when he accommodated the group’s request for a ride was that they had previously agreed to rob whomever picked them up.

As they rode together in Mr. Schwartz’s car, petitioner Gerlaugh, who was already on probation for robbery, suddenly pointed a firearm at his host and forced him to drive to a deserted area near Mesa, Arizona. We borrow from the third opinion of the Arizona Supreme Court to relate what petitioner and his confederates then did to rob Mr. Schwartz not only of $37.00, but also of his life:

The police interrogated petitioner Ger-laugh after his arrest, and he confessed to his participation in these crimes. When asked how he felt after he killed Mr. Schwartz, his chilling answer was, “How do you feel when you kill game?” Id. He added that he did not feel bad at all about killing the victim.

In a joint trial with Encinas, a jury convicted Gerlaugh of armed robbery, kidnapping, and first degree murder. 1 In addition to receiving sentences of twenty-one years on *1031 the armed robbery and kidnapping offenses to run consecutively with a sentence of thirty-five years to life for violation of his robbery probation, Gerlaugh was sentenced by the trial judge to death for the murder.

Petitioner Gerlaugh’s case comes to us on appeal from a denial in the district court of his petition for habeas corpus. His presentation to the district court contained fifty claims, but here he advances only ten. We have examined these claims and the voluminous record in this case, and we find them to be without merit. 2 Accordingly, we affirm the district court.

I

Guilt-Phase Claims

Gerlaugh advances three claims related to the guilt phase of his trial. The district court examined each in detail and concluded that they lack merit. We agree. Accordingly, we limit our discussion of them to a brief explanation of why they fail in the context of federal collateral review.

A.

Gerlaugh claims that the state trial court committed “fundamental error by refusing to instruct on lesser included offenses reasonably supported by the evidence,” namely (1) second degree murder, and (2) theft. His theory of defense, which was presented to the jury and covered adequately by an instruction, was that his use of intoxicants negated the specific intents required for the crimes with which he was charged. As legal support for his argument, he refers us to Beck v. Alabama, 447 U.S. 625 , 100 S.Ct. 2382 , 65 L.Ed.2d 392 (1980), and Vickers v. Ricketts, 798 F.2d 369 (9th Cir.1986), which hold generally that in a capital case, a court must instruct on every lesser included offense for which there is in the evidence a substantial factual basis. See also Hopper v. Evans, 456 U.S. 605, 611 , 102 S.Ct. 2049, 2053 , 72 L.Ed.2d 367 (1982) (“[D]ue process requires that a lesser included offense instruction be given only when the evidence warrants such an instruction.”); Spaziano v. Florida, 468 U.S. 447, 456-57 , 104 S.Ct. 3154, 3160-61 , 82 L.Ed.2d 340 (1984) (holding that court need not give lesser'included offense instruction where statute of limitations had run on those offenses).

We note first that “[u]nder Arizona law ... there is no lesser included homicide offense of the crime of felony murder since the mens rea necessary to supply the premeditation element of first degree murder is supplied by the specific intent required for the felony.” State v. Arias, 131 Ariz. 441, 443-44 , 641 P.2d 1285, 1287-88 (1982). But more fundamentally, even if we were to assume that such instructions as requested by the defendant should have been given to the jury, we can discern no “substantial or injurious effect or influence” from the failure to do so. Brecht v. Abrahamson, 507 U.S. 619, 623 , 113 S.Ct. 1710, 1714 , 123 L.Ed.2d 353 (1993). Notwithstanding his use of intoxicants, the evidence of Gerlaugh’s actual intoxication was extremely weak, and the evidence of his intent to kill, to rob, and to kidnap was overwhelming-especially that coming from his own detailed confession. In it, Gerlaugh acknowledged to Detective Weiss that (1) his intent in hitchhiking was to commit robbery; (2) he consciously made a decision “to kill Mr. Schwartz so as not to be identified by him for the robbery;” (3) his intent in causing the left rear wheel to spin on Mr. Schwartz’s body was to kill him; and (4) when the tire strategy failed, “[h]e exited the car to go over and finish killing Mr. Schwartz.” Gerlaugh also acknowledged ending up with Mr. Schwartz’s money and refusing to share it with his partners. Thus, the critical elements of the offenses with which Gerlaugh was charged were proved by overwhelming evidence. Accordingly, this claim must fail.

B.

Gerlaugh’s next claim, citing Bruton v. United States, 391 U.S. 123 , 88 S.Ct. 1620 , 20 L.Ed.2d 476 (1968), and Cruz v. New *1032 York, 481 U.S. 186 , 107 S.Ct. 1714 , 95 L.Ed.2d 162 (1987), is that his Sixth Amendment right to confrontation of witnesses was violated by the admission into evidence of the confession of his nontestifying codefendant, Encinas. We note first that Encinas’s and Gerlaugh’s confessions were nearly identical. At the time Gerlaugh’s conviction and sentence became final, Parker v. Randolph, 442 U.S. 62, 75 , 99 S.Ct. 2132, 2140-41 , 60 L.Ed.2d 713 (1979), did not bar the statements of codefendants from evidence so long as they were “interlocking.” Cruz altered this rule in 1987. Second, Gerlaugh has never challenged the accuracy of his confession; in fact, he admitted to the probation officer writing a pre-sentencing report for the trial judge that it was correct. Accordingly, and assuming that Encinas was unavailable to testify, under Cruz and Lee v. Illinois, 476 U.S. 530, 545 , 106 S.Ct. 2056, 2064 , 90 L.Ed.2d 514 (1986), his confession was properly introduced as admissible hearsay. But even if we assume that its admission was error, we conclude that the error was harmless by any standard because the codefend-ant’s confession was thoroughly reliable and consistent with Gerlaugh’s own description of the homicide. Indeed, portions of it were even helpful to him.

C.

Gerlaugh’s third claim has to do with the admission into evidence of (1) the admittedly gruesome photos of the decedent, and (2) the testimony of Mr. Roche, who evidently had been hypnotized prior to trial. On examination of these issues, we conclude as did the district court that they are not cognizable in this proceeding. Neither allegation raises the spectre of fundamental unfairness such as to violate federal due process of law. See Estelle v. McGuire, 502 U.S. 62, 67-68 , 112 S.Ct. 475, 479-80 , 116 L.Ed.2d 385 (1991) (federal habeas relief does not lie for state-law errors but is limited to violations of federal constitutional rights). Mr. Roche was unable notwithstanding the hypnosis to identify Gerlaugh at trial, and the remainder of his testimony, which was not about the murder of Schwartz, was virtually unchallenged.

II

Penalty-Phase Claims

A.

Gerlaugh’s most vigorous claim, one that divides this panel and requires our heightened attention, is that the representation he received from his appointed counsel in connection with the sentencing aspect of his case was not only ineffective, citing Strickland v. Washington, 466 U.S. 668 , 104 S.Ct. 2052 , 80 L.Ed.2d 674 (1984), but so defective that it was as though he had no counsel at all. For the latter proposition, Gerlaugh directs our attention to United States v. Cronic, 466 U.S. 648 , 104 S.Ct. 2039 , 80 L.Ed.2d 657 (1984). Cronic holds that if counsel fails to subject the state’s case to “meaningful adversarial testing,” then prejudice to the client will be presumed. Id. at 659 , 104 S.Ct. at 2047. These Sixth Amendment claims Gerlaugh brings against his lawyer rest not only on what he says his counsel should have done but did not, but also on what counsel did do but allegedly did very badly. We note in passing that counsel for Gerlaugh was certified in Arizona as a specialist in the practice of criminal law. Gerlaugh’s was his eighth death penalty case.

1.

The Failure to Call Witnesses

The first aspect of Gerlaugh’s ineffective assistance claim is that his counsel knew of but failed to call as witnesses during the sentencing hearing three people who could have related relevant mitigating sentencing evidence to the court: Bertha Parkhurst, Helen Sanders, and Ramona Button. This same claim was first examined in detail in a post-conviction proceeding in State court. The post-conviction proceeding included an evidentiary hearing and was conducted by the same trial judge who had sentenced Ger-laugh to death. 3 At the hearing, the three character witnesses in question testified as to *1033 what they could have said had they been called at the original presentencing hearing. In the main, the picture they presented of the petitioner was of a boy who had taken care of their children and pets without incident and who had displayed to them at least no violent or unpleasant tendencies. One of the witnesses buttressed her testimony with a vignette about Gerlaugh avoiding and showing concern for a snail on which he might have stepped, which suggests in context only that he had more respect for mol-lusca than people. The witnesses had no explanation for petitioner’s recent brutal conduct which was the subject of his trial. Ger-laugh’s father was also called to testify that, although he believed he was a good father, he was a very strict disciplinarian.

The judge at the conclusion of the post-conviction hearing found that this evidence was insufficient to establish good character as a mitigating circumstance. Moreover, Gerlaugh’s trial counsel was aware during the original trial of these cumulative witnesses and what they had to offer, but he made a tactical decision not to bring them into the case because of the questionable probative value of their testimony. He believed the testimony could backfire because it could indicate that although Gerlaugh was capable of compassion, he reserved it for animals, not human beings. Instead, trial counsel painted at sentencing a more direct and sympathetic picture of his client by calling his parents to the stand, and by interviewing six of petitioner’s friends from school and then causing brief summaries of the information gleaned from them to be incorporated into petitioner’s presentence report as mitigating evidence. In fact, the parents’ testimony drew upon and incorporated in large measure what the three witnesses would have said about their son.

Under the circumstances, we believe that counsel’s performance during this critical aspect of the sentencing phase was not deficient. He did what he could with what' he had to work with, which was not much. Furthermore, this particular allegation does not involve potentially favorable evidence about which counsel was oblivious. Counsel knew about the evidence and looked into it, but chose as a tactical matter not to use it. A reasonable tactical choice based on an adequate inquiry is immune from attack under Strickland. 466 U.S. at 689-91 , 104 S.Ct. at 2065-67 .

In any event, even if we were to assume to the contrary, we agree with the Arizona Supreme Court and the district court that no prejudice can be shown based on counsel’s choice not to call these witnesses and to proceed as he did. See Bonin v. Calderon, 59 F.3d 815, 823 (9th Cir.1995), cert. denied, — U.S. —, 116 S.Ct. 718 , 133 L.Ed.2d 671 (1996) (“[wjhere the aggravating circumstances are overwhelming, it is particularly difficult to show prejudice at sentencing due to the alleged failure to present mitigating evidence.”).

2.

The Failure to Use Psychological Evidence

The second aspect of petitioner’s ineffective assistance claim is that counsel failed as part of the sentencing process to develop and to use psychological evidence on his chent’s behalf. In support of this allegation, petitioner presented the testimony of Dr. Thomas O’Brien, a psychiatrist, at the post-conviction evidentiary hearing. On Gerlaugh’s behalf, Dr. O’Brien testified that petitioner suffered from a character or personality disorder called soeiopathy to the extent that petitioner’s capacity to conform to the requirements of the law was grossly impaired. On the other hand, as the Arizona Supreme Court remarked,

144 Ariz. at 459 , 698 P.2d at 704 .

For four reasons, we discount the effect of counsel’s failure to develop “Dr. O’Brien’s *1034 testimony” (or its equivalent) prior to petitioner’s sentencing.

First, as held by the Arizona Supreme Court, the evidence of petitioner’s “mere character or personality disorder like sociop-athy is not alone sufficient to constitute a mitigating circumstance.” Id. (citing State v. Richmond, 114 Ariz. 186, 197-98 , 560 P.2d 41, 52-53 (1976)).

Second, although such psychiatric evidence is normally relevant and admissible because it may suggest some reason other than the disorder itself why the defendant should be treated with leniency, the trial judge hearing this evidence at the post-conviction hearing held that it did not establish a mitigating circumstance. The Arizona Supreme Court on review agreed with this conclusion. Parenthetically, the trial judge remarked during the post-conviction hearing that the picture painted by Dr. O’Brien of Gerlaugh conflicted dramatically with the evidence presented by Gerlaugh’s three character witnesses referred to earlier in this opinion:

(Emphasis added).

Third, petitioner specifically had informed counsel before trial and with the full knowledge that his life was in the balance that he “did not want to undergo a psychological examination because he did not want someone prying into his mind. Petitioner never indicated to defense counsel any time thereafter that he changed his mind about this decision.” 144 Ariz. at 459 , 698 P.2d at 704 . Here is what counsel had to say about this issue during the State post-conviction hearing:

We note that Gerlaugh has never challenged this testimony. Petitioner’s personal wishes in this regard are entitled to respect. See Jeffries v. Blodgett, 5 F.3d 1180, 1197-98 (9th Cir.1993) (counsel not ineffective for acquiescing in defendant’s wishes regarding the nature of his defense); Bonin v. Calderon, 59 F.3d at 834 (“[T]he presentation of expert [psychiatric] testimony is not necessarily an essential ingredient of a reasonably competent defense.”). In addition, the trial judge in the post-conviction proceeding entered a finding of fact that “Petitioner had failed to establish that he was willing to have psychiatric testimony presented at the sentencing hearing.” About this issue, the Arizona Supreme Court said:

144 Ariz. at 459 , 698 P.2d at 704 . We agree.

Appellate counsel for Gerlaugh and our respected colleague in dissent fault trial counsel-in what sounds like a new rule pre-eluded by Teague v. Lane, 489 U.S. 288 , 109 S.Ct. 1060 , 103 L.Ed.2d 334 (1989)-for not revisiting with his client the issue of such an examination after conviction and during the preparation for sentencing. The argument is that trial counsel should have pressed his client on this issue and tried to get him to change his mind. Trial counsel has no recollection of having made such an attempt. But even if we were to regard such a lapse as a mistake, it would be of no consequence in this case because we know what counsel would have .found, and, on balance, we judge it to be potentially more harmful to petitioner than it could have been of substantial assistance in avoiding the death penalty. As the trial/post-eonvietion hearing judge and then the Arizona Supreme Court remarked, Dr. O’Brien’s testimony revealed petitioner to be a person who associated with “wild companions” and who “sought out the company of lawbreakers for the thrill of hurting others and then escaping the consequences of his actions.” 144 Ariz. at 461 , 698 P.2d at 706 . We agree with the Arizona Supreme Court that this evidence has “obvious countervailing tactical dangers for petitioner.” Id. at 459 , 698 P.2d at 704 . In its best possible light, it is a basket of cobras. Accordingly, we can identify no prejudice flowing from counsel’s failure to develop Dr. O’Brien’s testimony. Had counsel pressed his client and discovered this information, it is highly likely that the damning report would have remained confidential. See Bonin, 59 F.3d at 834-36 (the use of expert psychiatric testimony opens the door to powerful cross-examination and rebuttal).

Parenthetically, given this court’s approach to a lawyer’s introduction of potentially damaging evidence against his own client, one would certainly understand the reluctance of counsel to introduce any two-edged swords into a case. See Wade v. Calderon, 29 F.3d 1312, 1323 (9th Cir.1994) (the introduction by counsel of damaging testimony against a client suggests ineffective assistance of counsel). Had trial counsel introduced Dr. O’Brien’s testimony into this case, no doubt we would be hearing now a claim based on Wade that it was a serious mistake for counsel to have informed the sentencing court *1036 that his client was a remorseless predatory bully who victimized innocent people for thrills and who killed for status. Only in an appellate context can a lawyer safely reveal such unflattering evidence about his client without immediately damaging him, and this is because on this issue, the lawyer is on trial, not the client.

Fourth and finally, to send this case back to the state trial court to hear the evidence counsel failed to develop or to introduce-including the three witnesses as well as the doctor-would be a looking-glass exercise in folly. The trial and sentencing judge has already considered all of this information in the post-conviction hearing and has held that none of it would have altered his judgment as to the proper penalty for Gerlaugh. And, the Arizona Supreme Court looked at the substance and results of the post-conviction proceeding and affirmed the trial judge in all respects. In effect, petitioner has already had what he is asking for-consideration in a formal hearing of this evidence. We respectfully decline to order the State courts to do again what has already been done.

Petitioner does argue that because the trial judge was being asked at the post-conviction hearing to change his final judgment, he should have been disqualified. This argument is facially unsound. “It has long been regarded as normal and proper for a judge to sit in the same case upon its remand, and to sit in successive trials involving the same defendant.” Liteky v. United States, 510 U.S. 540, 551 , 114 S.Ct. 1147, 1155 , 127 L.Ed.2d 474 (1994). If fashioned into a rule, Gerlaugh’s argument would result in unnecessarily dislodging trial judges from post-conviction proceedings on the false assumption that trial judges are not capable of doing what the law requires. In our court, we have on rare occasion remanded cases to different trial judges, but never in circumstances as benign as presented in this case. Such a new rule of constitutional command not only makes no sense, but could not in any event apply to Gerlaugh. See Teague v. Lane, 489 U.S. 288 , 109 S.Ct. 1060 , 103 L.Ed.2d 334 (1989) (a new constitutional rule of criminal procedure may not normally be applied to cases on collateral review). We cannot identify any fault with Arizona’s rule that assigns post-conviction review matters to the original trial judge. See State ex rel. Corbin v. Superior Court, 138 Ariz. 500, 503 , 675 P.2d 1319, 1322 (1984) (enforcing rule).

3.

The Failure to Plead for Leniency

We move now to a nonevidentiary aspect of counsel’s sentencing phase performance, the claim framed in Cronic terms that counsel’s oral argument to the sentencing judge was so weak and deficient that, in effect, Gerlaugh was left without the Sixth Amendment representation to which he was entitled. Appellate counsel argues that this alleged failure to beg for leniency is presumptively prejudicial and requires a reversal, regardless of an absence of demonstrable prejudice. The argument is tantamount to a claim that such a discrete deficiency, although a trial error, is structural and thus evades harmless error analysis.

At the outset, although we have discussed each aspect of Gerlaugh’s claims against his lawyer separately, we do not believe it to be appropriate to segregate counsel’s oral presentation on behalf of his client at the sentencing stage of the proceeding from the other measures taken on his behalf. Under the Cronic test, it is the totality of his efforts that we must examine, not just part of them in isolation. “[Specified errors made by counsel ... should be evaluated under the standards enunciated in Strickland." Cronic, 466 U.S. at 666 n. 41, 104 S.Ct. at 2051 n. 41. Accordingly, we examine the steps taken by counsel on Gerlaugh’s behalf to try to protect his client from the death penalty; and we begin with counsel’s explanation of his approach and strategy as he testified during the post-conviction hearing:

At the presentencing hearing conducted on February 4, 1981, counsel began on his client’s behalf by attacking the applicability of two of the aggravating circumstances. He argued that because Mr. Schwartz’s money was taken after the killing, no robbery had occurred. Counsel also argued that notwithstanding the gruesome evidence adduced at the trial, the killing of Mr. Schwartz was not cruel or heinous as compared to other murders because no evidence was offered that Gerlaugh and his companions intended Mr. Schwartz to suffer, or that he was tortured. Counsel argued that although the evidence taken in the light most favorable to the prosecution demonstrated “an intent to kill this person[,] ... [t]here was no attempt to try to torture this person. Any of the acts that you may find to be atrocious was simply meant to murder the victim and not to actually make him suffer prior to then making the decision to simply kill him.” Strongly implied in this argument, of course, is counsel’s position that the death penalty was not appropriate for his client.

Counsel then called to the stand Ger-laugh’s parents, both of whom testified in mitigation that their son had been while growing up a model baby-sitter; a companion to an elderly woman; a Cub Scout; a squad leader in the Boy Scouts “moving to an Eagle Scout”; especially kind to animals, dogs, and guinea pigs; a normal family member; good to his sister; a worker; but also someone who seemed to fall under the bad influence of his codefendant, Matt Leisure, and then marijuana.

We reiterate here that prior to the presen-teneing hearing, counsel asked his client and his client’s family for a list of witnesses who would be willing to testify on Gerlaugh’s behalf. The record shows that he tracked down these leads, caused them to be interviewed, and then called to testify the witnesses he believed would be most helpful. He submitted materials regarding the others to Mr. Ed Delci of the Adult Probation Department so that Mr. Delci could include their statements in a supplemental presen-tence report.

Moreover, counsel vigorously took exception to the conclusions in Mr. Delei’s written work to the effect that Gerlaugh showed no remorse for his criminal behavior. Counsel argued directly to the court on behalf of Gerlaugh that Mr. Delci’s report was defective, that his client did accept responsibility for what he had done, and that he did demonstrate remorse in his own way. Furthermore, counsel emphasized his client’s age as “one large mitigating factor” in connection with court’s decision as to his sentence and assaulted Mr. Delci for not doing a thorough job. Here is what counsel had to say in this connection on behalf of his client.

On the judgment day, counsel made another attempt to derail the death penalty by waiting until sentence had been imposed on the non-death charges and then interrupting with a claim of double jeopardy.

Although this attempt failed, it conclusively demonstrates that counsel had neither deserted nor forsaken his client, and that as an adversary he was reaching for everything he could think of, even straws. We note that a similar claim of double jeopardy was filed as Claim 7 in the district court as part of this petition, but abandoned on appeal. We are not satisfied in Cronic terms that counsel “entirely fail[ed] to subject the prosecution’s case to meaningful adversarial testing.” 466 U.S. at 659, 104 S.Ct. at 2047.

Gerlaugh argues that his trial counsel was required by the Sixth Amendment to ask the *1042 sentencing court for leniency. This claim has no merit. When we examine as we must this alleged nonstructural deficiency for prejudice, we see clearly that no amount of theatrics could have made any difference in this case. Darrick Gerlaugh sentenced himself to death when, while on probation for robbery, he mounted and led a savage and relentless attack on Scott Schwartz designed to kill his victim and to save himself from prison. Ger-laugh knew full well from previous experiences with the law what awaited him if he left a live victim behind. When a vicious beating couldn’t accomplish his merciless objective, Gerlaugh used Mr. Schwartz’s own car to run him down, over and over. One can only imagine the terror Gerlaugh’s helpless and outnumbered target must have felt as he scrambled for his life on that lonely road. But ramming Mr. Schwartz with a moving vehicle was not enough either, so Gerlaugh decided to shred him to death by placing the car’s tire and its weight on him, while Mr. Schwartz was still alive, and then popping the clutch. How Mr. Schwartz managed to survive this brutality is hard to comprehend, but he did. A single-minded Ger-laugh, however, was not finished. As Mr. Schwartz pleaded for his life, Gerlaugh located a screwdriver and repeatedly plunged it into Mr. Schwartz’s face and neck until he drained him of his courageous hold on life and his tenacious will to survive. One need not ponder at length to realize what fate awaited Mr. Roche had he not escaped. Live robbery victims were not on Gerlaugh’s agenda, especially those who could place him in the vicinity of the Schwartz murder.

Against this barbaric behavior, Gerlaugh could muster no substantial mitigating circumstances, and he has been unable to do so to this date notwithstanding the dogged efforts of his able attorneys. The best his parents could do was suggest that in his younger days, he had been kind to his elders, to dogs, and to rodents. To review this scenario and to examine the photographs of the screwdriver wounds on Mr. Schwartz’s battered and mutilated corpse, all for $37.00, leaves us with a thorough understanding of why the trial court said, “The crime and particularly the manner of its commission was shockingly evil and grossly bad as well as being marked by debasement and preci-sion_ This offense absolutely demonstrates the defendant’s total lack of regard for human life or human suffering.” In turn, the Arizona Supreme Court said in its independent review .of the evidence regarding aggravating and mitigating circumstances:

State v. Gerlaugh, 135 Ariz. 89, 90 , 659 P.2d 642, 643 (1983).

Given all of this, we are confident that no plea for mercy or leniency on Mr. Gerlaugh’s behalf, indeed no oral argument on his behalf, could have altered what Mr. Gerlaugh himself set in motion. Even Gerlaugh’s age does not help him because he was adjudged mature by the trial court. Under Arizona law, the implications of the age of a defendant are considered in the light of his prior criminal history. In discussing whether Ger-laugh’s age was a substantial mitigating factor, the Arizona Supreme Court noted that

144 Ariz. at 461 , 698 P.2d at 706 (brackets in original). Parenthetically, this incident gives *1043 considerable substance to Gerlaugh’s analogy of killing game to killing people.

Accordingly, Gerlaugh can show no prejudice from his attorney’s sentencing performance, and “no substantial and injurious effect or influence” from anything counsel did or did not do. Brecht v. Abrahamson, 507 U.S. at 623 , 113 S.Ct. at 1713-14 . Even without the deference or the presumption of adequate assistance mandated by Strickland, 466 U.S. at 690 , 104 S.Ct. at 2065 , we cannot identify any aspect of counsel’s performance that “so undermine[s] the proper functioning of the adversarial process that the trial cannot be relied on as having produced a just result.” Id. at 686 , 104 S.Ct. at 2064. Faulting counsel for failing to plead for his client’s life would inject a mandatory element requirement into final argument, which is not evidence, and would “narrow the boundaries of acceptable argument style too much.” Hendricks v. Calderon, 70 F.3d 1032, 1045 (9th Cir.1995), cert. denied, — U.S. —, 116 S.Ct. 1335 , 134 L.Ed.2d 485 (1996). As the Supreme Court said in Cronic , “If there is no bona fide defense to the charge, counsel cannot create one and may disserve the interests of his client by attempting a useless charade.” 466 U.S. at 656 n. 19, 104 S.Ct. at 2045 n. 19.

4.

Summary

In conclusion, regarding the evidentiary aspect, of counsel’s performance in connection with his client’s presentencing hearing, we find no separate or cumulative deficiencies, but even assuming the worst, no prejudice. Moreover, given the facts and circumstances of this case, counsel’s overall performance at the sentencing proceeding was not deficient either. Compare Cooper v. Fitzharris, 586 F.2d 1325, 1333 (9th Cir.1978) (observing that “prejudice may result from the cumulative impact of multiple deficiencies”). But again, even if we look at it in the worst possible light, we are unable to discover any prejudice to Gerlaugh. See Strickland, 466 U.S. at 687 , 104 S.Ct. at 2064 . He is unable to show that absent the “errors” of which he complains, “the sentencer ... would have concluded that the balance of aggravating and mitigating circumstances did not warrant death.” Id. at 695 , 104 S.Ct. at 2069. The hard record had been made, the die had been cast, and we cannot conceive of any rhetorical flourish that could have made a difference. As we see the record, counsel’s task was virtually impossible. He did not abandon the defense of his client, and he did the best he could with a horrific case. His performance during the guilt phase was vigorous and intelligent. If the mouthpiece has no trumpet, blowing with all one’s might will not tear down any walls.

B.

Petitioner contends next that the statutory aggravating factor of an “especially heinous, cruel, or depraved” homicide, used to support Gerlaugh’s sentence of death, see A.R.S. § 13-703(F)(6), is too vague to survive scrutiny under the Constitution, and that it had not been given an adequately narrow construction by the Arizona Supreme Court prior to this ease which would enable it to escape this defect. In the vernacular of the profession, this issue has come to be known as the (F)(6) issue. See Walton v. Arizona, 497 U.S. 639, 690 , 110 S.Ct. 3047, 3076-77 , 111 L.Ed.2d 511 (1990) (Blackmun, J., dissenting). However, it is no longer novel and has been authoritatively settled not only by the Supreme Court in Walton , but recently by this circuit in Woratzeck v. Stewart, 97 F.3d 329, 333 (9th Cir.1996): the Arizona Supreme Court adequately narrowed the (F)(6) factor not in 1983 in State v. Gretzler, 135 Ariz. 42 , 659 P.2d 1 (1983), but in earlier cases decided prior to 1978. See State v. Mata, 185 Ariz. 319, 324, 322-327 , 916 P.2d 1035, 1040, 1039-43 (1996) (“Gretzler did not present a new, narrower interpretation of the (F)(6) factor, but simply a digest of the previously legitimate applications of the factor.”). Thus, because Gerlaugh’s final sentencing occurred after Gretzler , we are satisfied that he received the benefit of the properly narrowed construction of the (F)(6) factor as approved by the Supreme Court in Walton . Finally, the record demonstrates that petitioner’s assertion that there was no adequate finding of the (F)(6) aggravating factor is plainly without merit. Both the trial court and the *1044 Arizona Supreme Court adequately addressed this requirement.

C.

As to a second aggravating factor that the offense was committed for pecuniary gain, see A.R.S. § 13 — 703(F)(5), petitioner complains (1) that the evidence adduced at the trial did not support the finding, (2) that the facts relevant to this factor were inappropriately considered as to both the (F)(5) and the (F)(6) factors, and (3) that the Arizona Supreme Court “wholly dispensed with conducting an independent review” of this factor. The record does not support these allegations. We note as did the district court that the sentencing court said the following in a special verdict:

This finding is clearly supported by the petitioner’s confession and was adequately reviewed and affirmed on appeal. Moreover, the question of double counting not only is not supported by the record, as observed by the district court, but is a matter of state law and not cognizable in this forum.

D.

A third aggravating factor rendering Gerlaugh eligible for the death penalty is his prior robbery conviction for which “a sentence of life imprisonment or death was imposable.” See A.R.S. § 13-703(F)(1). Ger-laugh’s complaint is that three months after his conviction in 1978 for robbery, the Arizona legislature reduced the penalty for robbery to a maximum of five years.

There is no doubt that Arizona law permits the use of Gerlaugh’s prior robbery conviction in connection with the (F)(1) factor, see State v. Tittle, 147 Ariz. 339, 343 , 710 P.2d 449, 453 (1985); and that ends our inquiry. There is nothing about the change in the maximum sentence for robbery after Gerlaugh’s conviction that makes the use of the life sentence he was actually given offensive or arbitrary under the Constitution.

E.

Petitioner claims that neither the trial court nor the Arizona Supreme Court properly considered the statutory mitigating circumstances advanced on his behalf. The district court parsed out this assertion and the evidence to which Gerlaugh points, and 'found the claim to be wanting. So do we. We find in the record adequate consideration of his age, use of intoxicants, cooperation with the police, intent, good character evidence, and the life sentence of his unequally-culpable eodefendant. Guided by our holding in Clark v. Ricketts, 958 F.2d 851, 858 (9th Cir.1992), that “[t]he due process clause does not require that the sentencing court exhaustively document its analysis of each mitigating factor as long as a reviewing federal court can discern from the record that the state court did indeed consider all the mitigating evidence offered by the defendant,” we conclude that due process is satisfied. See also Parker v. Dugger, 498 U.S. 308, 314, 318 , 111 S.Ct. 731, 735-36 , 112 L.Ed.2d 812 (1991) (statement by sentencing court that it considered all mitigating evidence adequate); Jeffers v. Lewis, 38 F.3d 411, 418 (9th Cir.1994) (en banc) (no due process violation where it was evident that the trial court considered all mitigating evidence), cert. denied, 514 U.S. 1071 , 115 S.Ct. 1709 , 131 L.Ed.2d 570 (1995).

F.

Gerlaugh’s complaint that he was denied a “meaningful proportionality review” is belied by the record. The Arizona Supreme Court held that Gerlaugh’s sentence was proportional to the sentences imposed in other cases, see State v. Gerlaugh, 135 Ariz. at 90, 659 P.2d at 643 ; and the Supreme Court has held that we have no warrant to “look behind that conclusion.” Walton, 497 U.S. at 656 , 110 S.Ct. at 3058 ; Martinez-Villareal v. *1045 Lewis, 80 F.3d 1301 , 1309 (9th Cir.), cert. denied, — U.S. —, 117 S.Ct. 588 , 136 L.Ed.2d 517 (1996).

G.

Petitioner next attempts to elevate alleged errors in Arizona’s post-conviction relief proceedings to federal constitutional status. This attempt fails under Franzen v. Brinkman, 877 F.2d 26, 26 (9th Cir.1989), where we held that errors concerning such a process are not cognizable in federal habeas proceedings.

III

Counsel’s Performance on Appeal

Gerlaugh’s counsel made a deliberate tactical decision on appeal to address only those issues that related to the conviction that rendered his client eligible for the death penalty. Counsel’s objective was to render his client’s confession inadmissible and thereby to win a new trial. His best professional assessment of the case was that if his client suffered a conviction as charged, a sentence of death was almost inevitable. We find no fault with this assessment. With this diagnosis in mind, he did not address any issues pertaining to sentencing. He did so with the understanding that Arizona statutory law required the Arizona Supreme Court to make an independent examination of the propriety and legality of the death penalty. The district court correctly viewed counsel’s decision as a valid tactical choice not to dilute strong arguments with weak ones. See Jones v. Barnes, 463 U.S. 745, 751 , 103 S.Ct. 3308, 3312 , 77 L.Ed.2d 987 (1983) (recognizing the importance of “winnowing out weaker arguments on appeal”); Hendricks, 70 F.3d at 1042 (“The choice to pursue a bad strategy makes no comment on an attorney’s judgment where no better choice exists.”); Miller v. Keeney, 882 F.2d 1428 , 1434 n. 10 (9th Cir.1989)(defense counsel does not have a constitutional duty to raise all nonfrivolous issues). Moreover, we agree also with the district court’s view that the Supreme Court’s thorough independent review, see 135 Ariz. 89 , 659 P.2d 642 , erases any probability that the fate of Gerlaugh’s appeal would have been different had counsel raised in that forum the penalty-phase issues that are raised here.

AFFIRMED.

. Because the trial court suppressed co-defendant Leisure's confession, the State offered to him a plea agreement which he accepted.

. Because Gerlaugh’s petition was pending in federal court prior to the enactment on April 24, 1996 of the Antiterrorism and Effective Death Penalty Act of 1996, we use the "old law" to decide this case. See Lindh v. Murphy, — U.S. —, 117 S.Ct. 2059 , 138 L.Ed.2d 481 (1997).

. Originally, the evidence was developed in front of another judge, but the matter was than transferred to Judge Brown who considered the transcript of the previous hearings.
