Kaido when about to die, sees everyone say shit about him and thinks about Oden and Whitebeard and says "all I pursued was dying in a great way but I never thought that your death will never be great if you dont live a great life, I should have put more thoughts on Living as great person than dying in great way"
this would be great character moment for him, and this is also a great message to provide to teens(whom shonen is directed towards)
