Well, I think Kaido is a bad character, you are right when you say we didnt get character development, but for me it aint bad, yet it also is a top tier character as you mention.
And you are wrong, Kaido never saw himself as Joyboy, he just said that Joyboy will be the guy who defeats him, it was King who saw him as Joyboy.

I don‘t remember really at all.
