Which again has nothing to do with oden about to kill kaido and getting robbed of that chance
the scabbards dont want to beat kaido they want him dead
zoro has inherited odens sword and will
as shown in 954 irc that swords carry will from their fallen owners
He inherit Odens sword, thats it, not the will. The most important question is always: WHY
WHY do the scabbards and oden and luffy want to beat Kaido? To bring freedom to Wano.
Why does Zoro wants it? For two reasons, cause his captain wants it and because Kaido is a strong foe and he wants to get closer to WSS. None of Zoros motivations match Odens.
