Spoiler for like, any book existing.
I think mine has to be the villain in Mirror Man. Idk, he wasn’t intimidating, he wasn’t interesting. He was meh.
Also the villains from The Chain. Dear God they weren’t sympathetic in the slightest. The book tries to act like they were atleast pitiful but FROM THEIR INCEPTION, they were just evil assholes who enjoyed causing pain. The book itself wasn’t all that great anyways.
Patrick Bateman. If you’ve only seen the film, he is way worse in the book.
Him killing the kid in the zoo made me have to quit the book for a while. It was all horrible and disgusting, but the way he’s so casual about it. I had to stop again when he meets a girl, and revels in the fact that he has raped her with a can of hairspray and she was afraid of him. Still terrifies me
