Luffy said its stupid to die for some one you love and respect , same way he tried to die for ace by going to marine Ford. Same way ace died for him
sanji wanted to die for the wrong reason, in his eyes he was repaying a debt and out of gratitude, it's stupid and weak, he shouldn't repay zeff by killing himself but rather by pursuing/achieving his dream.
luffy and whitebeard's crew sacrificed themselves to save ace, to save the life of a brother/son/nakama, there's nothing wrong with that, that's not repaying any debt, they're not doing it out of gratitude or for it.
jinbe is like jinbei he also wanted to save aces out of gratitude for whitebeard protecting fishmen island.
now, if sanji wanted to save baratie out of love or kindness, that's totally fine, that's how luffy gets motivated to save people, they give him food, he likes them, and he helps them, it's not to return their favor.
Sanjis only problem has being relying on others. Yes he was a traumatised kid who had no-one he could turn to that is why it is hard for him to rely on others .
relying on others was never a problem for sanji, WCI is special because sanji didn't want his personal past to cause trouble for his crew, also his sacrifice was meaningful because it was out of kindness, he saved his abusive siblings even though he doesn't owe them anything, that was badass ngl.
Roger is the best example pk but could not achieve what he wanted cos he gave himself up for death.
wrong, roger failed because he was 20 years early, have you even read oden's flashback?
Zoro and luffy have learnt not to die for their ambitions but to live and see it through.
that's just wrong, go re'rea zoro vs kuma,
and i'm sure you can find examples of luffy risking his life if you searched.
Mihawk told zoro not to rush and spared his life. Sanji told him to not rush and not face mihawk now cos he was physically weak. Basically same thjng different wording .
mihawk said that to zoro out of respect for zoro's strong spirit, while sanji said it out of fear for ones life, it's not even close.
