His prediction makes a lot of sense. Kaido wants to die a glorious death so it probably won't happen for him.
this video has some flaws
most obvious being @11:00 and his whole "villians in op dont get what they want"
Actually... they do, they just dont get the exact desire they want when we met them in their arc as a antagonist
villians in op get redeemed, or get things they want just not the one we knew they wanted in their arc about them.
like dofla's desire will be meet that marejois and WG will fall it just wont be seen by him so yes he got what he wanted just not 1:1 to his initial desire.
same is the case with Buggy and all his accomplishments, or Enel who is now leading a army of aliens, etc
the point is antagonist DO get what they want just not what they INITIALLY desired or EXACTLY what they wanted
Kaido not getting a WB type death doesnt mean he wont die, it just means he wont get revered as WB, Oden, or Roger. This is not a black or white situation. this is a gray one
and in which case he will likely die but with a whole different meaning and impact than what WB or oden had
