Whats a character you shouldn't find attractive but you do?

Any villains or toxic characters that you just have to stay silent about your simp when people are hating?
I'm sorry but the teacher from A Silent Voice is so hot like I understand he's a bad boy for not speaking up or stopping the bullying when thats the most important part of his job and he deserves a beating but.... LOOK AT HIM. I feel guilty for simping but... come oooon.
