Which film antagonists do you like?

[MurphysColeslaw]

Recently re-watched 'In the line of fire', which is one of my favourite 'junk' movies so to speak.
I really love the John Malcovich character and despite wanting it to all work out for Clint (Well why wouldn't you?) I have a strange admiration for the antagonist.
Who is yours?
And if you've seen the film, do you agree or not?

The bad guy in Ghostbusters is completely right. They shouldn't be blasting rays all over the city with no safety checks or safety protocols.

Hans Gruber.

Billy Loomis.

And Snape. And the Sheriff of Nottingham.

Sam and Dean
