There's two kinds of evil that horror fiction always deals with. One kind is the sort of evil that comes from inside people, like in Dr. Jekyll and Mr. Hyde. The other kind of evil is predestined evil. It falls on you like a stroke of lightning. That's the scary stuff, but, in a way, it's the stuff you don't have to worry about. I gotta worry whether or not I'm getting cavities. I gotta worry about whether cigarettes are giving me cancer. Those are things I can change. Don't give me lightning out of a clear sky. If that hits me I just say, "That's probably the way God meant it to be."
