I disagree with these answers. Around 20 years before The Dark Knight Rises takes place, The Pit was the savage den of aspiring child rapists who swarmed once they caught the scent of shaved-head, pre-pubescent Miranda. If I remember correctly, the entire prison wanted to rape her, except for her single protector: the kind and gentle-hearted Bane. Bane? If HE was the most empathetic man in that prison, then the rest of them were far from saints. I assume at least SOME of these men must have still been there, unless the League just murdered ALL of them—and I wouldn't blindly assume only innocent men were dumped into the pit from that point on. I mean, it's in the middle of some middle-eastern city. Obviously that city still had use of the pit, and I'm sure they wouldn't just stop dumping criminals in there. And, why would we assume that Bane and his followers were guards there? He was rescued by the League, and then eventually excommunicated. Did he decide he wanted to go become a prison guard? There were no guards. Supplies were lowered down by the rope. Regardless, Batman definitely freed a few rapists/murderers, and probably contributed to some more rape/murder.
