Kaido is like that sometimes
he want to stand as a great pirate, strong and courageous standing with his captain and strongest crew member
He wants to be like them for a part
like he wanted a great and noble fight with Oden and Luffy
But ended up chucked each time and ended up lesser than Xebec and WB too
He has no one to blame but himself, he never outgrew his childish mentality that might makes right and needing to see himself as the strongest.
He never could understand what is it that made Roger, Whitebeard and Oden great men, or even pirates.
For all his strength, authority and power, he ultimately ended up being just another drunken fool not knowing what he is doing with his life.
