A person experiencing a fullblown psychotic episode is beyond the point of self control, and frequently self recognition. It’s a seriously rare occurrence, and it usually doesn’t result in the death of anyone but the sufferer. I just think the distinction should be made between people who may be highly disturbed or psychopathic, or on a revenge streak or whatever reason they have, and people suffering a very serious mental illness that in the midst of an episode wound up killing somebody.
