I know the popular take is Batman's rogues getting their butts handed to them by Bruce Wayne, and I'm not belittling that, because that's really funny for all stated reasons?

But how about a new take: most of Batman's rogues call him off limits, because they find out he is their benefactor, when/if they try to reform?

Mr Freeze won't touch him because when he's in Arkham, Bruce is the one who finances the research to help Nora Fries.

Poison Ivy won't touch him because he had been the one supplying her with plants, while in prison.

Harley won't touch him because he's just a great guy an' gotham needs guys like that.

Riddler won't touch him because he was the secret backer that time Eddie tried to open a detective agency.

Croc won't touch him because he's one of the few people who ever talks to him like a person.

Deadshot refuses any hits on him because he found out Wayne does a lot of secret work for people down on their luck who made bad mistakes.
