There are still a missing piece in Kaido's character. And I still think its related to Yamato. He did mention he didn't even want Yamato to get the fruit.
He changed somewhere between GV and the Oden fight where he only wanted to die. and I also think it's related to Zoro. Shimotsuki is just a red herring and Zoro is related to Kaido bu was taken away from him wich made Kaido flip. He probably wanted a son instead of Yamato because he thought Joy boy must be a man. Wich connect to Zoro story with Kuina being a similar case to Yamato. This is how Oda did with Sanji story, he came back to the original flashback and fleshed it out. I am dying on the hill that this is the true twist when Kaido comes back
