What is the evilest Disney Villain? What Disney villain is the evilest?

I think Scar from the Lion King :P he's one of the few in a Disney movie to be successful with killing someone during a movie

To me, Bill. He trys to kill children, doesn't care about the end of our world, and rips deer teeth right out of a deer's mouth. Yep, definitely Bill.

I think Maleficent is really evil.
