I'm not disturbed that she killed them. Obviously its just a movie. I'm disturbed that Mike seems to think they deserved it, when in fact, they didn't. May is not supposed to be a hero!
I tell ya though.....even if I didn't have any friends my whole life, I really don't think I'd kill a bunch of people and make something out of their body parts...that doesn't come about just from loneliness...that requires some kind of mental problem.
