"Okay. Well, it goes like this: somebody dies, and they get stored unconscious in the middle of a room until a judge decides to come look at them and wake them up. The judge reviews the entire history of their life, and if they were practically perfect they get to go Upside, and if they weren't they go Downside, and if the judge doesn't like them they go Downside and get assigned a sentence of some number of hours of torture, the record is twelve. And torturers can't easily quit - judges virtually never bother assigning sentences to anybody who's already sorted, because they'd have to notice and care that you were doing something, but if a torturer stops doing their job the judges will keep sentencing them until they reconsider. There is a loophole to make this whole system less completely shitty: a sentence has to be served by somebody, but it doesn't have to be by the person it was originally for; anyone else can decide to take it for them, and it counts as long as the substitute sincerely means to be a substitute. I'm one of the people who does that. We're called contractors."
