Some of them can't be helped or don't want to be helped. You look at the ones who have been in and out of jail their entire lives, arrested dozens of times for the same offense, etc. There comes a point where you have to assume that they simply don't give a damn. To be fair, there are people who might have screwed up once and could turn things around with a second chance. Do we make it too difficult for people to reacclimate to society after serving their sentence?
