Funny but Kaido was also alone with King vs Shanks and his crew but we should shit on him for not suiciding there.
If Kaido thinks Shanks is not strong enough why did he run away from Shanks and his crew instead of fighting them just like he fought scabbards?
This is why Kaido is a shit character. He says shit that he himself does not believe.
He's a more delusional version of Don Krieg
