Bryce, actually there are many rehabilitation programs for prisonners. They have group sessions, work with therapists, some even train seeing eye dogs to learn to care about something that loves them back. While this therapy does not work on all, it definitely does work for many. The rate of reoffending is about 60%, so that means 40% are rehabilited (or aren't caught for other crimes). Which isn't great. but it's better than nothing.
