You are like one of those cult people or religious nuts who overanalyse a word to make it fit your biased narrative and justify your views. You and a decent number of people on this forum are gonna have hard time accepting that Oda just isn't that deep.
Zoro isn't taking the MC of One Piece's glory and focus away from him. No a 12 year argument of Zoro vs Kuma doesn't justify it because it was done to highlight something very specific about Zoro's character: that he's willing to die for Luffy.
So no, you are giving me perspective on jack shit lol. ZKK at that point is some weird desperate accomplishment for Zoro "fans" who believe that completes Zoro as some justified executioner. Like that has some weird bearing on being a higher accomplishment than Luffy getting a full fight and winning.
This was like how Sanji fans went into complete meltdown mode when Oda trashed their expectations and he ended up just baking a cake for BM. Don't put all your eggs in a flimsy ass basket, it's not my fault you and half the cult sub have deluded yourselves into believing in some sort of prophecy like its the rapture
