Man it's preety funny that Reddit was so against Zoro killing Kaido, but is willing to jump on the Zoro Kills King or Zoro Kills Orochi for some reason.
Zoro kill king theory runs fine due to the fact that he is currently fighting him and after medicine effect vanishes, he won't be able to move.
Zoro kill Orochi is backed by the incident that happened when yasui was killed.
Whereas the zkk theory is based on "comparatively weaker" premise of Ryuma comparison and final boss is always defeated by Luffy.
P.S- I fully support ZKK and I want that kaido fucker to be cut in pieces by zoro senpai ❤
