Serial killers are usually—virtually always, in fact—slaves to their own compulsions. They kill because they have to, and they can't stop themselves. I don't want to get to that point, so I set up rules about smaller things—like how I like to watch people, but I don't let myself watch one person for too long. If I do, I force myself to ignore that person for a whole week, and not even think about it.
