I don't think i'd ever define a PERSON as evil. Mental impariment is VERY difficult to diagnose. It's one thing when someone says God told them to kill, or "the voices" told them to kill, but what about people who kill "because i felt like it" or "because it was Wenesday and i always feel like it on a Wednesday" or "because i wanted the insurance money"? Clearly their thinking is skewed, not normal, but is it an impairment?

One could say that only someone who is not thinking straight would deliberately kill another person, so where does that leave us?
