RIght!? With the whole Kaido waiting for Joyboy and Kaiod and King being direct victims of the WG, I expected Oda to go down this route at some point, at least Kaido giving the WG hell before he goes/is taken down. I expected the WG and Marines to launch a major assault on Wano and Kaido to potentially make a final stand there, defending Wano, acting like Joyboy and Ryuuma ironically and living up to the guardian deity role he was meant to play due to his fruit as well. Thus Oda could give Kaido a Whitebeard style sendoff if he wanted to, let him try to redeem Kaido in death, desptie the horrific atrocities Kaido made when he was alive ofc.
A lot of OP villains are just imitating the WG in the same kind of BS they do, the same evils, the same cruelties, its ironic really. Some of them despite the WG and yet parrot them so much.
It would have been so catharthic if we could have seen Big Mom and Kaido rampaging against the WG and Marines, along with their crews too. King getting revenge especially too, not just for his own torture and cruel experimentation but the actual genocide of his race entirely, all but him and thus using him to create the grossly insulting Seraphims too.
