When the Villain Wins an Oscar

When supporting characters are not that 'supporting' ... when the leads lead a selfish crusade in the name of greed, cruelty or a wicked vision of power ... or when the darkest sides of the human soul inspire powerful and unforgettable perforamances allowing the villain to have a final revenge... and take the Oscar home.

Which of these oscar-winning performances as a real-life or fictional villain is your favorite?

(PS: Vito Corleone isn't included not because he's a good guy but to call him a 'villain' in the film's narrative would make no sense, his son Michael was a villain in the second opus, although a tragic one)
