I have 2 examples.
Ill share one; my stepdad was always a huge piece of shit. He still is, actually. He’d trick us into eating tomatoes. Me at 12 could eat them, whatever. My 5 year old brother was forced to eat them, and got grounded if he didn’t. He would actually force us to eat foods we didn’t like and would literally backhand us across the face for “disrespecting” that we had food on the table.
I worked at a sub shop that had the hottest of the sauces. I told a similar version of this story to my boss, and got my hands on an illegally 'hot" sauce. I poured the whole bottle into a store-bought salsa i knew he’d eat.
Jackass that was a huge piece of crap for several years and repeatedly stole things was a part of a larger social group I was a part of. Used to gaslight and attempt sexual assault on most of the girls in the group too, and his various lies tended toward causing fights.
Literally got the chance and spent a weekend banging his (divorced) Mom.
Side irony: getting the chance like that to spend quality time with an attractive gal boosted my self image enough I was able to later make some of his hidden transgressions against that community apparent. Much of the group ostracized him, and the ones that didn’t fell away as they often were complicit… Grooming girls or equally abusive etc.
