Cope, J. concurring.

Several errors are assigned:

The defendant’s counsel then asked this witness the following question : “ At the time Cordes gave the pistol to Sweeney, was anything said by Sweeney with reference to using the pistol against the defendant, Philander Arnold ?”

To this question the counsel for the people objected, on the ground that it was irrelevant and incompetent.

The Court decided that the testimony was inadmissible, unless evidence was produced tending to show that the thing said had come to the knowledge of the defendant, and sustained the objection; to which decision the defendant excepted.

We do not understand that the testimony rejected-was offered for the purpose of proving a threat on the part of the deceased. It is clear that the mere fact that one man threatens to kill another is no sort of justification to the latter to kill the former. The threats must be shown to have been communicated to the accused before they are admissible for any purpose (and then the effect and bearing of the testimony should be explained by the Judge to the jury before the case is finally *481 submitted to them). In this case there is no pretense that this threat, if there was any, was so communicated. The ground taken by the defendant’s counsel is, that the question presented to the jury by the proofs was the question of fact as to which one of these parties first assaulted the other; and the defendant contended that the deceased was the aggressor in the fatal rencounter, and had placed defendant in danger of his life, from which peril he could only extricate himself by slaying his assailant. The counsel contends that any fact which con duces to show that this theory is true, was legitimate evidence, and that this fact of the declarations of Sweeney at the time of borrowing the pistol does so tend. The object of a trial is to elicit the real state of the transaction, and the rules which govern or determine the introduction of testimony have relation to this end. These rules are not mere arbitrary, conventional regulations; they are founded in reason and good sense. Generally speaking, whatever has a tendency to prove a material part of the issue is admissible. This proof may be direct or inferential, circumstantial or positive. It may be more or less conclusive, but if it be relevant, this want of conclusiveness is no bar to its introduction. The question in this case, as made by the prisoner, was the fact of the assault by the deceased; and in a conflict of proofs, the solution of this fact was or might have been dependent upon a variety of considerations ; and these were to be passed upon, and the conclusions reached by the jury as the exclusive arbiters of this question. The defendant was entitled to urge all the considerations conducing to establish his theory and to disprove that of the prosecution, which could be fairly presented to the jury. He had a right to urge as well expressly proven facts, as the probabilities and inferences to be drawn from the conduct of the parties connected with the occurrence. He did urge, as we infer from the record, that this assault was not made by him, but that it was made by Sweeney; and to prove this, he proposed to show that Sweeney had armed himself with this pistol; that he had borrowed it, and that it was found at the place of the rencounter. He was permitted to show these facts, but he proposed to show a further fact, and that was, that at the time of Sweeney's getting the pistol, he declared what he meant to do with it. This declaration, being made at the time of procuring the weapon, was a part of the res gestee, and illustrative of the transaction. It shows, in other words, the purpose for which the weapon was procured. This leads us to the inquiry, whether the fact that A procures a weapon for a particular purpose *482 conduces at all to show, in a question of conflicting proofs as to the manner in which he used it, what that manner was. We apprehend that if a man goes into a house, borrows a gun, goes out with it, saying that he means to use it on another, and a rencounter happens between him and that other, and the witnesses who see the difficulty differ, or the circumstances are equivocal as to which one of the two commences the affray, that some light might be thrown upon this question conducing to or towards its solution, by the proof of these facts as to A’s procuring it and his motives in doing so. The jury might possibly, with some reason, conclude that as the weapon was procured for this purpose of assault on another, that purpose was fulfilled; that the assault, in other words, was made in pursuance of the intended purpose when the weapon was procured, and especially if other facts in corroboration of this conclusion existed. It is true there would be nothing conclusive in this. But the fact of the conclusiveness of this proof to establish the proposition which it is introduced to prove, is not the decisive question ; that question is, whether this item of fact be a matter proper to be considered by the jury in arriving at their conclusion upon this mooted point. And we have no doubt that it is; that it may enter into the deliberations of the jury with all the other facts, as a matter to be weighed by them with the rest of the proofs.

4. We do not think it necessary to examine the point as to the instructions of the Court. The charge objected to, as we understand it, is this: That when the fact of a homicide is shown, then it is incumbent upon the defendant to show by a preponderance of testimony that the killing was justifiable. The authorities seem to hold this as a general proposition; but this proposition is subject to the qualification that where the testimony of the prosecution leaves a doubt as to the character of the homicide—as whether justifiable or not—then the benefit of the doubt is to be given to the prisoner. But the propriety of such an instruction as that given must necessarily be dependent upon the facts in proof, and the charge would be right or wrong according to the circumstances of the given case. We have not all the facts before us so as to enable us to pronounce upon this matter.

For the error indicated, the judgment is reversed and the cause remanded for a new trial.
