They agreed to help Luffy ‚ who put his life down for them even before they agreed to join him‚ not to assist someone who like Sanji who can finish the job easier than them
Everyone is repeating Sanji can't hit women but you keep ignoring it....
Im gonna say it again, everyone on the crew knows Sanji cant hit women, its his weakness, he has 0% chance winning against women, not 0.05% chance....0.00%. Zeff, who he owes his life too, told him it's wrong to hit women and thats how he lives his life.
Would you rather someone who has 0% chance winning a fight or someone with 10% chance?
To reply to your post, that's the stupidest thing I've seen...everyone is part of crew and they look after each other when someone can't do something. Reason why Nami fought Khalifa and now Robin being happy Sanji relied on her.
If you want Sanji to hit a woman, tell Oda.
I feel like I have to say it one more time, Sanji can't hit women. It's not easier for him compare to weaker characters because his chance of winning is 0%.
