Kizaru is holding back and is forcing himself to do things he doesn’t want to
Once he ups his resolve and fights for himself he’s going to look significantly better
Agree. But I’m not sure he can do it. Lets see.
Aokiji did it (v Akainu, then he wavered against Garp who called him out on it).
Zoros ambition and true nature was sensed by the likes of Mihawk and Kaido. Even King and Marco who had been around Kaido and WB sensed it and knew (more clear with King). But Zoro nearly threw it away because he went against his nature.
Ace did throw away his potential. He didnt think he deserved to live, who knows what he could have done with better sense of self worth (not to be confused with self confidence).
Luffy nearly threw away his ambitions due to depression. Jinbei, Hancock and Rayleigh woke him up.
Moriah threw it away.
Crocodile threw it away before regaining it.
Buggy threw it away before regaining it.
Arlong and Doflamingo kind of kept it but settled for less than maximum.
Kidd if alive…?
As Luffy says - the Pirate King is the most free man on the seas. I guess he means lives the way he loves, in accordance to ones true nature. And that is why WB really was the second PK, he loved his life where as BM and Kaido still tried to Building armys to reach their goals.
