Maybe he was doing it for Yamato as we all know she likes Ace. Anyway what do you think are the chances that Shanks only stopped Kaido cause he wanted whitebeard dead ?
Plus Shanks :
He only intervened after whitebeard and ace died.
He managed to stop the war with just a word.
He get personal meetings with the gorosei.
Why would Kaido even go to kill Whitebeard if he can leave the job to the marine ? Why the extra effort ?
Something doesn't feel right. Call me crazyβ but I won't be surprised if Im is shanks
