lol sanji has never shown to be having his dream more important than his life , last time i saw him he was bitching about dying just cause of ur ambition in zoro vs mihawk . every character is equally loyal ? lmao what rubbish , just reread the shit which happened with usopp, nami and ulti in the raid , tell me thats as much loyal as zoro who regards his ambition so high and still sacrificed it for luffy .
Who said that it's necessarily a good thing to consider a dream more important than your life, especially if the dream is based on the pursuit of self-glory, whereas the life itself you can use to help other people?
Sanji wasn't "bitching" about dying;
Unlike Zoro, who's willing to mutilate his own body as the first possibility of solution that comes to his mind in order to win and survive a bad situation (which led him to hurt himself pointlessly to Mr.3, and also almost to commit the same mistake if Usopp hadn't enough common sense to stop him), Sanji's difference is that Sanji is much smarter, so he could analyse properly the situation and reach the conclusion that the best option would be to ask Robin's help so he would survive, which would be good for himself and for his allies, since Sanji would be much more useful alive than dead. He asked for help partially for his won sake, but not for his own vanity, and the fact that he didn't mind the open humiliation of getting scorned for asking for a woman's help just made his attitude more praiseworthy, since he didn't allow some selfish pride to get in the way of much more important things, such as the importance of staying alive in order to be more helpful to all his friends in the war.
And the proof of his lack of selfishness in face of important things is the fact that he also went as far as to ask Zoro to kill him in case he were to lose his sanity and become a threat after his fight with Queen.
On the other hand Sanji never did something as pathetic as bowing to a man who was supposed to be his goal to surpass, like Zoro did.
To begin with, Luffy is not God, so I don't understand why people speak as if it were always necessarily an absolute good to sacrifice something for Luffy. And in that situation it was very far from necessary for Zoro to beg Mihawk like that. Even assuming that it was really necessary for Zoro to get much stronger and to help Luffy, he still had the option to train to get stronger on his own, without Mihawk's help.
