(b) A person who suffered from a condition of mind caused by mental disease or defect that prevented the person from forming a culpable mental state that is an essential element of a crime charged, but care should be taken not to confuse such mental disease or defect with moral obliquity, mental depravity, or passion growing out of anger, revenge, hatred, or other motives and kindred evil conditions because, when the act is induced by any of these causes, the person is accountable to the law.
