Oda hasn't killed any villain in the series so why do you think he'll start with the character whose dream is to die? Why do you want reward the bad guy?
Also why do you want Zoro to be the one to kill him? I mean we know that the battle against Kaido will be a group effort with Luffy in the lead so why do you want Zoro to kill him after Luffy knocks him out, Oh a sleeping guy lets kill him! you want Zoro to kill a guy whos already down?
I'm 100% sure that Zoro will cut him like Oden and it 'll be awsome but from that to directly killing him is a lot of difference, it's ridiculous
