Yeah but vivi actually needed help that’s why she’s with morgan and wapol she would have been done for if they aren’t with her so vivi didn’t figure it out on her own she found ppl to help
the majority thought vivi would be fine but the fuss was about Zoro’s argument not making any sense, ace was a strong pirate and had his crew to back him up, vivi tho has a weak nation and dead father, pell and the strawhats are pretty much all she has
And how do you help Vivi? To help someone, first you have to know how to help, the will is not enough.
Let's give the example of the Muguis going to Alabasta to "help" Vivi. As they are arriving she is announced that she will be publicly executed at headquarters for treason. You are no longer able to make it in time for the execution and she is dead.
Zoro at no time refuses to help Vivi, on the contrary, he says that they have to know how to help her first. Helping Ace was "easy", you "just" had to go to Impel Down or Marine Ford, you had a goal, not with Vivi. It has turned out that Vivi is safe and sound which is good, but nothing changes, even if she was dead or imprisoned or was going to be executed, Zoro's reasoning is still perfect. Hence the gang listened to him, because if Zoro was wrong Luffy would have gone to Marie Geoise.
