There's this OG NY movie Short Eyes, which is a good movie, but very disturbing, in all ways.
It's a jail in NYC called The Tombs and the cons find out there's a child molester in there and they all wanna kill him, but there's one guy who is just tired of all the killing, who tries to talk them out of murdering him.
Nah fuck that, kill that sonofabitch, which of course they do. There aint no coexisting with those kinda people.
Anyway if your interested in seeing it, it's on YT but, yeah you've been warned, it is not an easy watch.
