Kaido attempted to do this by destroying him in battle, torturing him to break his will, destroying his crew and humiliating his right hand man...And yet Kidd returned even stronger and eventually took down a yonko..it's a consistent pattern...And now Kidd has taken a big loss off the coasts of Elbaf...He's 100% returning back with an even stronger will and he certainly isn't quitting. In fact, his path mirrors another very important character, can you guess who?
Anyway Kaido couldn't break his will and Shanks won't be able to either. He's a Conqueror for a reason.
