Read please, for what more they would do. Not talking about killing or convicting on suspicions alone, or even fantasies alone (even though fantasies always precede action), but keeping away from society, people who have already started, because once someone is started, it's pretty damn hard for them to stop - cause hey, they already aren't innocent.

I wrote a lot of sick fuckery for the kink meme, but I've never DONE it, there is a difference between fantasy and reality. I can't imagine why I would ever cross that doorway considering the consequences, people getting hurt, my conscience, that reality is never as satisfying as fantasy (and no kill would be like the first, but people will keep trying). But if for some reason I do, cross that doorway, is there any reason in the world at all why I would stop once I've started? To first start, you must justify it to yourself, and once you have, how do you fix that?

Ed Kemper was one of the rare ones who stopped himself, and to do that, he called the police.
