Comparing the circumstances from chapter 1 or 2 to how it is now… that’s not how things work villains aren’t the same, Luffy isn’t giving a nearly defeated Kaido his back and go like Zoro take his head or finish him or whatever.
it’s useless to argue so it’s easier for both of us to stop here and soon we gonna see who is right.
Read my ZKK theory on my signature.
Oden's flashback has a lot of parallels with Zoro's introduction arc.
First Zoro went that same route of believing the villain and doing something in exchange for everything being okay, but the villain was lying.
Then we have the fact that Oden lost because of a hostage situation, just like at the end of the Zoro introduction arc with Koby and Helmeppo, Kaido could do the same thing to Luffy after being defeated, just like he did with Oden, but this time Zoro will be there to help him, unlike Oden who was alone.
