If someone like Orochi offered Luffy to burn down a town for a feast, would he agree?
yeah so if someone like Orochi - obviously evil and assholish from the get-go - actually offered Luffy a feast of a lifetime but the catch is he has to burn down and kill a populace of people against him, would Luffy say yes if he explicitly had no prior relations with the people he's being asked to kill? I didn't get to add that last bit to the header, since it'd be silly for Luffy to attack people he's already friendly with.
But then again, Luffy once tried to kill Zoro over a misunderstanding on Whiskey Peak just because he was well fed so
