^^ A few of those actually have some of my sympathy and pity. But I won't list names.

Valentino from Hazbin Hotel. He makes everyone else here seem like a saint.

Homelander from the Boys is a nasty piece of work

Theo Galavan from Gotham

Aunt Marge

Also Ridley (especially in the manga)

Judge Claude Frollo.

I actually found Frollo pretty cool, but i do understand your answer.

Ramsay Bolton and Brian Irons. Both of them are extremely misopedistic sick f**ks.

I so understand why people liked Frollo as Hellfire was a pretty good song. The Coachman is another good candidate.

The Coachman is a good answer, while Frollo was pretty cool, The Coachman was just nasty.
