Unfortunatly in the real world your criminal justice ethics will have to accommodate crimes that are not murder, so you might need to think about some prisoners eventually getting released, who might then go on and do more criming.
> it's great if they change their life but ultimately it's to extract murderers from society
In that case, there is no need to make prisons particularly cruel. Cost can be debated, but surely as a society, we can put a value on humaneness. Even if not, if say I, a billionaire, wanted prisoners eat caviar every night and am willing to fund it, surely this should be allowed.
