Which he won't be getting though since he's a "bad" person. He'll die in a country that isn't connected to the outside world so they'll just read about his death in the newspaper.
exactly. but we'll get a rocks flashback so that oda can build that narrative and end it with his pathetic death.
also another thing: we see luffy & big mom claim that they wanna become the king of the pirates. but kaido even though he declared that he wants to find the ancient weapons and the one piece, he has never said he wants to become the king of the pirates.
all he is dreaming of, is to die a honourable, grand death so that people remember him long after he has passed like roger and whitebeard. this is the other part of the theory.
EDIT: to die a honourable, grand death, in the process of finding the one piece and ancient weapons
