Looking for recs featuring well-illustrated villains or antagonists that got under your skin

(Not literally illustrated)

Hi! I am looking for books or stories where any character really got under your skin. The types that make you angry for the main character or maybe even remind you of someone who f*cked you over in your own life.

Fiction, memoir, true crime, creative nonfiction, whatever genre works. I'm just interested in thoughtful illustrations of people doing shitty things, conniving, manipulating. Especially interested in anything more covert, slow-burn, and subtle. Also specifically interested in psychological fiction and memoir but not excusively by any means.

Thanks, and please no spoilers of any kind!!!
