I still cant understand that.
I mean, if Kaido is beaten and unconcious, maybe near death, Zoro will be absolutely able to kill Kaido physically. But at best will, i cant imagine Zoro going for it when Luffy refuses to. Zoro knows the character of Luffy and Luffys decisions are the decisions of the crew. So Zoro is taking Luffys decision. Overgoing Luffys decision to not do the killing blow comes close to a betrayal against his captain, something Zoro would never do.
