Knave of Hearts (Disney)

The Knave Of Hearts is one of the main villains of Tim Burton's Alice In Wonderland and although he feigns loyalty to the Red Queen he is in reality even more antagonistic than the mad tyrant and plays upon her insecurities in order to skillfully manipulate her into doing what he wants.

However at the end of the film upon being sentenced to being banished for eternity with the Red Queen the Knave Of Hearts attempts to kill her, which shocks the Red Queen at first (as she was geniunely in love with him) but quickly infuriated her as the two were dragged off to the wastelands where they presumably remained for eternity or until they killed one another.
