G U Y S i couldn't remember all the stuff about kemper so i looked up his wikipedia page and read some more about his imprisonment and B R O he didn't just bully mullin he was literally manipulating him emotionally so he'd act a certain way im-
it said that mullin liked to sing a lot and kemper threw water on him to shut him up and he said "then, when he was a good boy, i'd give him peanuts... that was effective because pretty soon he asked permission to sing. that's called behavior modification treatment"
what the f u c k
edit:
HE'S STILL ALIVE OMFG
HE'S 71
