Theres a very real conclusion I have come too. With all the things I have seen in my life, the battles I have been in. There is such a thing as pure evil. Movies have a tendency of blowing it out of per portion well so you think. There is something Alfred says in the Dark Knight. There are some people that are motivated by the sheer pleasure of watch the world burn. It really doesn't sink in or make sense until you see someone like that.
Well, I have. But I am not going to let people like that change who I am.
