Cooper, J.,
delivered the opinion of the court.
The appellant has been convicted of the murder of James Fos-sett, and sentenced to capital punishment. The defense principally relied on in the court below was that, at the time of the homicide, appellant was insane by reason of an attack of mania a pota, resulting from prolonged and excessive use of intoxicating liquor. Many errors are assigned, but we note only such as may be of probable importance in the further prosecution of the indictment.
On the trial of the cause, Dr. R. A. Quin was introduced as a witness by the defendant to prove the character of the defendant for peace or violence, and also as an expert to prove the symptoms and characteristics of mania a potu. On cross-examination by the district-attorney, and over the objections of the defendant, the district-attorney was permitted to ask the witness the following question : “ Do you know whether or not he [the defendant] has ever killed a man before ?” And over like objection the witness was permitted to answer: “ I have heard that he had.” The defendant *237then moved to exclude the question and answer, which motion was by the court denied. This testimony, if admitted at all, must be so either because it was competent as tending to show the intent with which the accused shot Fossett or to attack his character for peace, or to disprove the defense of insanity. If there anywhere appeared in the record anything to suggest that the purpose of the testimony was to show that the declaration of the accused, testified to by one witness for the state, at the instant of the killing, “ this is the third son of a bitch I have got,” was a sane remark, relating to actual occurrences of the past, then remembered by the accused, a different question would be presented for consideration. The defense of insanity opens a broad field of inquiry, and much evidence which would otherwise be incompetent is admissible, because of the nature of the issue presented. The defendant, claiming incapacity for crime at the particular time of the homicide, subjects all that he then said and did to such scrutiny and investigation as will show whether he then recognized and understood his relations to society, and the nature of the act done by him. If at the instant of committing one homicide he declares that he has previously committed others, and it be true that such others had been committed by him as he states, this statement indicates that he was then sane to the extent at least of remembering correctly what had before occurred, and thus furnishes some light for the solution of the question of his sanity or insanity. But the state did not propose to prove the truth of the statement made by the accused that he had before that killed two other persons. The manifest purpose of the testimony was to show either the motive of the accused in killing Fossett, or to attack his character for peace. In neither aspect should it have been admitted. The fact that the accused had on a previous occasion killed a man, could not prove any of the circumstances under which, or the act by which Fossett was killed, nor throw any light upon the intent with which the accused killed him. The defendant was upon trial for a distinct offense, and that offense not of the character of those in which it is admissible to prove an unlawful purpose by showing guilt of the same character on another and independent occasion. Against one on *238trial for passing counterfeit money or forgery, it has been held competent to prove guilty knowledge and purpose by proof of former acts of the same character; but it has never been held that the malice necessary to the crime of murder may be shown by evidence of the prior, independent and disconnected killing of another person. It is probable that the evidence was admitted upon the idea that it was competent by such evidence to attack the character of the accused for peace, to prove which the witness Quin was introduced, but, if this was the ground on which it was received, it was equally erroneous. One accused of crime may introduce evidence of his character such as would make it unlikety that he would commit the crime with which he is charged, and, having thus put his character in issue, it may in turn be attacked by the state. JBut neither the accused nor the state can resort to particular facts to establish or refute the character thus put in issue. The reputation of the person, or at most what particular witnesses believe of him from his course of life, defiues the limits of the rule. One who puts his character in issue is supposed to be prepared to defend it by showing such habits as to generally impress the community or particular persons who knew him favorably. But he cannot be expected to be able to defend particular acts, nor is it just that failing so to do, the burden of guilt in reference to a particular and disconnected transaction should be fixed upon him, and the motive or malice thus discovered imputed to the separate fact under examination. "Whart. Crim. Law, § 636 et seq.
The next error assigned rests upon these facts : Dr. J. H. Pur-nell was examined as an expert, and the defendant, for the purpose of establishing his defense of insanity, put to him an hypothetical question, the hypothesis consisting of facts which the evidence of certain witnesses tended to prove. This witness answered that, assuming the supposed facts to be true, the defendant was at the time of the killing suffering from mania a potu to such an extent that he could not distinguish between right and wrong. On cross-examination, the state’s attorney put to the witness this question: “ Immediately after he had shot a man, assuming it to be true that a man had shot another in a bar-room, and immediately afterwards *239lie had said, ‘This is the third son of a bitch I have got/ assuming it to be true that he had killed other parties, and that he had then walked down to another bar-room, and called for a drink and got it and said, (I have killed so and so/ naming the deceased, and that the defendant went home and was carried to jail next morning, and then gave a detailed account to another party immediately afterwards, and after he had seen his lawyers he stated to them, ¿ I ana advised by my lawyers not to make any statements/ would yon consider that man sane or not ?” The defendant objected to the question, and the objection was overruled. It is conceded by the attorney-general that the hypotheses stated, except what occurred at the place and time of the killing, were wholly unsupported by any evidence. The supposed facts were imaginary. Unless it be true that one accused of crime may be deprived of a defense recognized by the law as valid and entire if proved, by the fabrication of incriminating facts, the error here committed is palpable and fatal. No argument or observation by this court can give more prominence to it than its mere statement. 1 Thornp. Trials, § 606, and authorities there cited.
The tenth, thirteenth, and sixteenth instructions for the state are erroneous. By the tenth instruction the jury was told that if it had no reasonable doubt of the sanity of the accused at the time of the killing, “ then, if the jury believe the defendant shot and killed the deceased, they will find him guilty of murder.” In effect, the instruction was that if the defendant was capable of malice, the jury must convict upon proof only of the killing. The court practically settled, by its instruction, the existence of the material ingredient of murder- — -the malice aforethought of the accused.
The thirteenth instruction is clearly upon the weight of evidence, and therefore should have been refused. By it the jury was told that “ a jury is not warranted in inferring that a man is insane from the mere fact of his committing a crime (if the jury believe such was committed by him), or from the enormity of such crime, or from a mere apparent absence of adequate motive that may or may not appear for it, for the law presumes from a killing with a deadly weapon a bad motive, and that it is prompted by malice, if *240nothing else appears in evidence.” This instruction is a copy of a part of the charge given by Judge Cox to the jury in Guiteau’s Case, 10 Fed. Rep. 161, and, it is said, properly advises the jury of the insufficiency of the facts therein recited to warrant the inference of insanity. It seems to have been forgotten by court and counsel that the rule which obtains in England and in the courts of tire United States, under which the judge is accustomed to express his views upon the weight of the testimony, is by our statute expressly denied. By our code (section 1714) it is declared that “ no judge, in any cause, civil or criminal, shall sum up or comment on the testimony, or charge the jury as to the weight of evidence,” etc. Inferences from the facts are to be drawn by the jury, unaided and uninfluenced by the court. Our statute means this, or it means nothing. If juries, turning aside from the direction and control of their own judgment, unworthily submit to the impulses of passion, compassion, or prejudice, the responsibility is with them, but the court may not, to prevent any such supposed inclination, invade the province of the jury by informing it what weight should or should not be given to established facts.
By the sixteenth instruction for the state the court informed the jury that, in law, the defendant was responsible for his act if the jury believed that, at the time of the killing, “ the mind of the defendant was capable of knowing that if he shot the deceased, not in his own self-defense, he was committing an offense against the law of the land, and it will not matter what the jury believe was the moral conception of the defendant of the act at the time.” "VYe suppose it was intended by this instruction to adopt to its full extent the doctrine of McNaghten’s Case, 10 Clark & F. 200, that one who acts from an insane delusion is criminally responsible if the imaginary facts would not, if real, excuse or justify the act. This standard, accepted by this instruction of sanity, or rather of responsibility of the insane for acts committed by them, excludes the test of capacity to distinguish between right and wrong, and imposes upon the insane the exact responsibility that rests upon the sane, with the single exception that the facts imagined by the insane to exist are for the purposes of his trial to be treated as real. *241No matter, said the court to the jury, what “ was the moral conception of the defendant of the act [meaning, we suppose, his capacity to distinguish between the right and the wrong], you must convict if the defendant knew he was violating the law of the land.” It will not avail to contend that one who has sufficient capacity to know that he is violating a human law must also know that the act also violates a divine or moral law. The instruction assumes that such is not the case, and declares that one not having the capacity to distinguish between right and wrong is liable to criminal responsibility. The rule announced in Cunningham v. State, 56 Miss. 270, that one who knows and recognizes the difference between right and wrong is criminally responsible, and one who does not is not, is, by the instruction here given, materially and erroneously modified.
Reversed and remanded.
