Rehabilitation? No, a justisce system exists to protect the honests from criminals.
The main reason a justice system exists is to protect honest people from criminals avoiding self-justice and revenge. It means criminals needs to be separated and put where they can cause no arm for enough time, and to disincentive them from keeping on.
Rehabilitation should be a side effect of the system. Useful, if you can reduce the number of criminals, but if you made it the main aim (mostly based on religious beliefs, including the religion called socialism), the justice system starts to fail spectacularly, and honest people are utterly damaged.
Especially since criminals are trained to cheat. Many of them will cheat easily those who wish to rehabilitate them - usually people with so many prejudices it's really easy to cheat them - and keep on being criminals - because some people simply prefer crime to an hard working life.
There should be much more emphasis on preventing people becoming criminals, than trying to rehabilitate them afterwards (just, you'll always have true criminals). Yet, even "rehabilitation" can be a real business for many people...
