Okay guys, so for this question you can't pick a character from Game of Thrones just because I'm pretty sure everyone would pick Joffrey, but for me an actor who Played a villain so convincingly That people can't see them as anything else would have to be Emile Dastelton who plays professor Umbridge and Harry Potter She was just the worst.

I am yeah I would have to agree with you the actress that played Umbridge was like a perfect fit because she was not likable at all

Okay I wouldn't say villain but Tariq from power like when he was like younger that guy was the most annoying guy ever and people just want a streak
