I was pretty indifferent to Hiyori prior to this info but I actually kinda dislike her now. That declaration is actually hella messed up.
I had similar issues with where Neji's plotline in Naruto went (as well as some stuff with the Uchiha) but I didn't expect this kinda stuff in One Piece out of nowhere. Oda sat down, wrote Orochi's backstory where he's persecuted and chased after for his grandfather's crimes and then just has his demise involve perpetuating the notion his family was inherently awful? Nah. Ace and Robin's story and the conclusions to their character-arcs highlight both that simply existing and being you isn't a crime and that the actions of your forefathers aren't yours. I'll stick with those messages.
