Some that come to mind are Bill Cipher and the 4 MB (Dudley Smith, Hans Gruber, Green Goblin and Harry Lime).
Dr. Facilier and most versions of the Joker. Dimentio too.
I mildly hate green goblin for framing his own son and breaking his arm
Most versions of the Joker, Bill Cipher, Hans Gruber and Lucifer (Supernatural).
Bill Cipher
Zhan Tiri
Dimentio and Porky
Dimentio, Bill Cipher, Sir Benedict Cumbersnatch and pretty much any other laughably evil villain (with the exception of Scar, but I don’t hate him).
Bill cipher
Heath Ledger Joker, his portrayal was excellent, despite how his actions were, they were impressive, that he was a little more serious and his quotes.
What do you think?
