I will say that it's easy for us to be sympathetic, when we see their "human" side, but that sympathy dries up, real quick, when we are victims.
I have worked with both perpetrators and victims (often, the same person).
It's pretty heart-wrenching. There's no practical solutions on the table. It's pretty difficult to get folks behind efforts to reform things.
In the US, a felony rap is a "scarlet letter" that follows people throughout their entire life, destroying any real chance at true reform. Pretty much guaranteed recidivism. Dishonorable military discharges are another one.
I have heard that the UK has a system that "shelves" criminal records after a certain number of years, and only employment in certain fields (like law enforcement, childcare, etc.) can view the records.
