Hmm, after re-reading the chapters, I think Luffy might be a special case, as he did save a Fishman and hit one of the most hated groups of people to the Fishman. Still, I suppose if some truly nasty humans who really are enemies of humanity are offered it, they might join.

Maybe that's what Cariboo might do this Arc.
