Barto was a troll, people said omg he is evil, he is going to throw a bomb at us and it was just a stink bomb, he is just obnoxious, an asshole, his cannibal moniker is exactly a reflection on that, he mocks/irritates people.
I don't know his mafia past but in terms of piracy it seems he is just obnoxious and his "evil feats" were exagerated becuase of that.
mafia family that rules several cties seems enough for me to be considered a criminal
and no reason to think he got tender passing to piracy@D:
Yup it seems to annoy a lot of people here but we are reading a pirate manga right? The strawhats are "good guys" but still try to not look into thinks it terms of black and white. Think of the wars that Luffy can start for meat, or the unnamed marine fodder that "lost his eye from a zoro slash", or that wallet nami might have stolen once upon a time. All this didn't happened in the manga, but they could happen if we take on account the character traits. Its not the same as a beheading or a tongue cut, but the morale of a pirate and the personal motivation, could justify such actions in context.
well it's not that..hell luffy made tons of criminal evade from impel down..criminals that probably have done terrible things and deserved to stay in prison..so it's not like luffy is a "good guy",he mostly acts selfishly..if he thinks you are a jerk,he shoots you down,if he likes you,he will help you,but he doesnt' really have an high level of morality
the problem here though,is that this guys are gonna go around the world "under his flag",it's less collateral damage and more beign actually responsible for those guys
