[Batman] Do the villains (Joker, Scarecrow, penguin, etc) in Gotham exist because of Batman or would they still be around if he wasn't?

I remember there was an episode in the Animated Series that brought this question up.

It's been brought up numerous times, the answer is both are true.

Many minor crooks have tried to gain an easy rep by getting a gimmick.  

It's been established that Bats 'created' the Joker by dropping the Red Hood into that vat of chemicals [comics, not Nolan Universe.]

Poison Ivy, Scarecrow, Mad Hatter, Croc and Penguin had agendas/psychosis prior to meeting the Caped Crusader.
