While I can see your point, gotta disagree on this one.
WB the whole world witnessed his death. He got a final big FU to Sengoku and the WG by saying the One Piece exists. People will rmmbr him by this.
Kaido on the other hand won’t get this since villains in OP don’t get their dreams fulfilled as you probably already know. Kaido wants to die a legendary death akin to Rogers, WBs, Odens. We also know he will not go anywhere but Wano whether it’s by choice or force. He has the die. And his death will be due to his own faults of stagnation in a secluded country isolated from the rest of the World.
I like how you tied Ace and Zoro tho, I didn’t think about that.
The thing is with Kaido, I still have this feeling that the phrase we've seen pop up in this series a few times, "The weak don't get to choose how they die." is going to pertain to him.
He's been given this perception that he is this unbeatable monster, considered to be the Strongest among the Strong by people throughout the entire World, but for some reason, throughout his entire life as a pirate, no matter how much he tries to seek his own death, it constantly ends in failure.
This is the missing piece of the puzzle for Kaido that needs to be addressed. If the strong get to chose how they die, then why does Kaido keep failing? I feel like this is going to be fleshed out in his flashback, and even did a theory on it awhile back linking it to Coby/Alvida's relationship, to possibly his and Big Mom's relationship when they were apart of Rocks, making the speculation that Kaido, before gaining his Devil Fruit, was in fact weak.
If this is the case, then Kaido will never die in a battle of his choosing, and that saying stated by Law and Doflamingo in the beginning of this entire Vs. Yonko Saga will have come full circle.
