If you are not sentencing someone to life in jail or the death penalty, then you can't treat a prisoner bad enough to cause lasting damage because they will rejoin society at some point.

This is irrespective of the victim's thoughts; if I get violently robbed and society + a judge has decided that's worth 10 years in jail, then that's what it is.

If you think prisoners deserve absolutely nothing to the point of causing psychological or physical harm then you are saying the crime they committed is worth life in prison or the death penalty.

This is assuming a functioning justice system.
