Yeah, that's one of the episodes that immediately came to mind.

Harley: There's one thing I've gotta know: why'd you stay with me all day, risking your butt for someone who's never given you anything but trouble?

Batman: I know what it's like to try and rebuild a life. I had a bad day, too, once.

It was absolutely a rehabilitative vision of justice. The same thing happens with The Ventriloquist, where Batman is extremely supportive, and goes to great lengths to talk him down after he was manipulated into returning to crime. Heck, there's even a villain, Lock-Up, who personifies a cruel, punitive form of justice. He even reveals the guard's abuse, through a clever ploy, as Bruce Wayne, in a hearing about Arkham.
