Evidence of a pertinent trait of his character, such as a moral quality, offered by an accused, or by the prosecution to rebut the character evidence; provided that such evidence shall be restricted to showing those moral qualities pertinent to the crime with which he is charged, and that character evidence cannot destroy conclusive evidence of guilt.  (2) Character of victim. (a) Except as provided in Article 412, evidence of a pertinent trait of character, such as a moral quality, of the victim of the crime offered by an accused, or by the prosecution to rebut the character evidence; provided that in the absence of evidence of a hostile demonstration or an overt act on the part of the victim at the time of the offense charged, evidence of his dangerous character is not admissible; provided further that when the accused pleads self-defense and there is a history of assaultive behavior between the victim and the accused and the accused lived in a familial or intimate relationship such as, but not limited to, the husband-wife, parent-child, or concubinage relationship, it shall not be necessary to first show a hostile demonstration or overt act on the part of the victim in order to introduce evidence of the dangerous character of the victim, including specific instances of conduct and domestic violence; and further provided that an expert's opinion as to the effects of the prior assaultive acts on the accused's state of mind is admissible; or  (b) Evidence of a character trait of peacefulness of the victim offered by the prosecution in a homicide case to rebut evidence that the victim was the first aggressor;  (3) Character of witness.

It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake or accident, provided that upon request by the accused, the prosecution in a criminal case shall provide reasonable notice in advance of trial, of the nature of any such evidence it intends to introduce at trial for such purposes, or when it relates to conduct that constitutes an integral part of the act or transaction that is the subject of the present proceeding.  (2) In the absence of evidence of a hostile demonstration or an overt act on the part of the victim at the time of the offense charged, evidence of the victim's prior threats against the accused or the accused's state of mind as to the victim's dangerous character is not admissible; provided that when the accused pleads self-defense and there is a history of assaultive behavior between the victim and the accused and the accused lived in a familial or intimate relationship such as, but not limited to, the husband-wife, parent-child, or concubinage relationship, it shall not be necessary to first show a hostile demonstration or overt act on the part of the victim in order to introduce evidence of the dangerous character of the victim, including specific instances of conduct and domestic violence; and further provided that an expert's opinion as to the effects of the prior assaultive acts on the accused's state of mind is admissible.
