[Batman] Has Batman ever actually helped anyone by sending them to jail?

The criminals always seem to want revenge, has there ever been anyone who was helped by the criminal justice system?

It depends on the continuity.

Harvey Dent was briefly rehabilitated during the "Hush" arc. 

Selina Kyle has gone from a greedy thief to a bat-family adjunct. 

Harley Quinn has also considered going straight (heh), but how much of that was Batman's doing is arguable. 

And it's safe to assume that, as in real life, plenty of the street criminals Batman has locked up decide to turn their lives around. 

We really only hear about the failures.
