I wonder if we adopt this viewpoint..what are people supposed to do with these people who are blankety, blank, blank........oops can't use the E word lol. If a person has zero empathy and takes pleasure is killing or tourturing a person...how does understanding them better help me. For some reason we're always analyzing and delving into the persons past to explain their behavior. True in some cases there might be a reasonable explanation for why a person behaves badly, but sometimes it doesn't have to be so complicated.

If a person wants to kill and eat me for dinner, I just want to get out alive. If it's not okay to call a person evil, then I guess we can't call anyone good either. Look at the Casey Anthony trial - everyone is speculating why she may have killed her child and why. They're all trying to blame it on abuse and no one seems to realize there are some people who kill beause they can, without remorse.
