Ten Scariest Movie Villains

As a speculative fiction author, I dabble in horror. Two of my best are Twisted Fate and Dream Hunters. Though the second leans more toward science fiction, the dreams contained in the story are pure horror. Today I came across a list on AOL of the ten scariest movie villains. Some of them I hadn't heard of.
Here's the list.
10. Ghost Face from Scream
9. Angela Baker from Sleepaway Camp
8 Jigsaw/Billy the Puppet from Saw
7. Chucky from Childs Play
6. Pennywise the Clown from Stephen King's It
5. The Firefly family from House of a Thousand Corpses
4. Michael Meyers from Halloween
3. Jason Vorhees from Friday the Thirteenth
2. Leather Face from Texas Chainsaw massacre
1. Freddy Kruger from Nightmare on Elm Street

I wasn't familiar with the Firefly family or Angela Baker, but the video clip from Sleepaway Camp looks intriguing; a bullied child takes revenge.
Another list from YouTube listed as top ten horror movie villains (doesn't mention scary)adds Norman bates from Psycho, Jack Torrance from The Shining, Regan from the Exorcist, and Hannibal Lector from Silence of the Lambs. They also had the Xenomorphs from Alien, but if your going to have that, you also have to put in the predator from the Arnold Schwarzenegger Predator movie. That one however may be less horror and more action/adventure. If I'm including action adventure, I might want to add Heath Ledger's Joker from the Dark Night and maybe even Darth Vader from Star Wars.

What do you think? Did I leave someone out? Who's your scary favorite?
