Who is the creepiest bad guy in the movies?

I watched this movie a while back called "Little Children" with Kate Winslet. There was a character, a registered sex offender named Ronnie, who absolutely creeped me out. His creepiness seeped into my dreams even. I don't know if I could ever watch that actor in another movie without remembering Ronnie.

Not of course a villian in a movie - but this reminds me of an episode of one of those news programs - Catching a child predator - where they set up a house with a teen that is on the internet and would-be child predators show up at the house and out comes the TV news reporter guy. One really creeped me out - he was a rabbi. It really creeped me out and made me feel ill.

Peter Lorre had a career full of creeps, but the creepiest of all was the child murderer in Fritz Lang's M
