But still, Zoro has not the slightest interest in fullfilling Odens wish, he doesnt share his ideals, his toughts, his motivation, nothing. There are only similar situations, all with different motivations. Comparing these 2, based on a few random situations doesnt make sense at all, when they dont even share at least one thought or goal. Specially when you have Luffy on the other side, which shares kinda the exact same motivation, while sharing the same ability about gathering people around him for the same goal. Also, Zoro is and never was a leader. He was alone wolf for some time and then he was a subordinate of Luffy (while i dont mean subordinate in a negative way). Zoro is no leader. Luffy is and Oden was.
