Sociopaths in film: Seven Psychopaths

I saw this film recently. I thought it was pretty funny, not terribly accurate? Probably the most interesting aspect of the film is how the psychopathic characters view the one empath character's alcoholism. They sort of wonder at it -- why might someone be drinking themselves to death. It doesn't make sense to them. And even though they are going around killing people, they express the same or more moral concern about whether or not the alcoholic should be driving drunk. It's a little hilarious because typical empath viewer would obviously think of the murdering as more serious than the drunk driving, but not the psychopath characters.
