The history of piracy is actually pretty interesting to dig into. They had a whole quasi-state going in the Carribean and were just as likely to recruit you as kill you, so there was definitely a moral code of some sort. From what I recall there wasn't a whole lot of inter-pirate competition and the closest you got was arguing about what to target during a particular season since a pirate ship was closer to a democracy in many cases than one might imagine.
