single line ruined his character. the situation got nothing to do with him and nami corrected him.
it shows development tho both lines
It has to do with him if he wants to, Nami is his friend for quite a long time and knows the story, and she lost her mom in the process. It's easy to get pissed with that, and if Sanji really meant something against Jinbe, he would've done something as he said before Jinbe spoke.
Sanji knows more than anyone the value of a mother, it's comprehensive for him to get pissed.
Not surprisingly Oda left Luffy and Zoro out of this scene, because he would've needed to highlight Luffy and Zoro reactions to the situation as well, like it mattered for them too.
Anyway, there are so many sentences i just don't know how to type them with the exact same words.
Probably the one he tells Usopp that everyone has something that they can and cannot do, and that there is no problem with that.
Maybe his speech to Germa, where he eats food from the floor, praises the sanctity of food, complains about them beating Cosette and also about royalty who treat subbordinates like inhuman objects.
Perhaps the one where he puts his pride aside to use the Raid Suit to save people.
There are too many.
