So...Luffy defeats Kaido in the end, with Kaido lying on the ground defeated without anything left in him.
Then suddenly a Zoro, post defeating King, jumps up to the rooftop and cuts off Kaido's head while Kaido is lying on the ground...
Luffy : What the fuck Zoro? Our battle already ended last chapter, and you take pride in slaying an already beaten villian? What happened to your honor?
Zoro: ZKK ZKK ZKK ZKK!!!
...yeah nope, Oda wouldn't pull off anything as retarded as something like this.
ZKK isn't gonna happen if Oda actually cares about Zoro's character.
If ZKK happens it would absolutely destroy Zoro as a respectable swordman. It is actually bad for him.
