It's not for the image in itself but what entails. There's a deep significance as Sanji is desperate looking to return to the SHs despite all the things he did.
Sure he was craving to make sure Zeff would not die and that's noble and still when Luffy acknowledged that Ace was in danger he preferred to trust him and simply stick to his nakama, that was a demonstration of strong will in that keeping his dream to become PK even more alive without even taking a deviation under such critical circumstance, good or not. In this case Sanji patently preferred to stick his neck out of the crew instead of trusting it more and try to find a solution to stem the BPM's dangerousness. He was saying goodbye to the All Blue.
dude, how can you compare these two situations. I am amazed.
Ace is already one of the most famous pirate about people in the pirate world at that moment. There's also whitebeard behind it. Could zeff and ace situation be the same?
The issue of trust in nakama is the issue that I am most nervous and tired of.
Remember . When Sanji first agreed to go, half the crew was not there . zou had already been destroyed. So leaving was not an option, it was a mandatory.
The purpose of going was to refuse the wedding and return. but when he came to the castle he learned why he couldn't give up this wedding.
When Sanji and Luffy got into a fight, there was no alternative to the current situation for Sanji. Either he would bring his crew with him and kill them all. or he would say he was leaving the crew. The point you missed was that at that moment, Sanji left the crew and asked them to come back. Luffy didn't do the same thing for usopp and didn't take it back until he apologized. but Luffy was stubborn about Sanji and didn't give up.
Then, Sanji agreed to go to the wedding knowing that he would die taking the word of his friend life from BigMom. So at that moment, Sanji had already accepted death, was insecure due to childhood traumas, and considered himself out of the crew.
So, Sanji's issue has nothing to do with trusting his friends. You talk so much that everyone was there when Sanji first came to be picked up, like Sanji turned his back.
Sanji wanted to save Zou and his friends by choosing death. Luffy is the stubborn one. You can understand how Luffy feels a special bond with Sanji here.
But , ı am bored anymore. trusting nakama , hit the Luffy , are you bored ??
