Sanji's character did not get ruined. Don't know where people got it from.
A lot of people wanted Sanji this chapter to do the generic
"I would rather die than talk" cool guy line.
But that's Pre-Timeskip Sanji
Sanji didn't wanna die a senseless death just because of his belief of not hurting a woman.
He had his friends that allowed him to keep his belief without dying.
That's what Strawhats do, they cover each other weaknesses.
That's why he trusted Robin can handle this
for him as he tries to save his own life so that he could go do something else.
Captain Hague from Fire Force explains this well.
If Sanji were about to die, then who will protect the Strawhats crew then? The main role of Sanji is to saves the weak. Now it's the other Strawhats' turn to save Sanji this time.
Characters that have no idea about Sanji's belief, think that a man calling for woman's help is pathetic and "unmanly" (notice how these characters get beat by Sanji easy).
While character like Marco thinks otherwise.
And of course the character that is affected by Sanji's actions the most- Robin, is the happiest we've ever seen her be and that's thanks to Sanji's actions.
So if Robin is happy that Sanji did this, I don't think anyone else's opinion matters on this matter.
Sanji isn't trying to be the generic cool guy like Zoro that would rather die than ask for help.
Sanji's actions are cool if you understand his character arc.
Sanji calling to Robin for help is great because it just reinforces that part of the reason the Strawhats’ side will succeed is genuine trust, friendship, and bonds.
Saying Sanji's character got ruined is just false if you know his character and what happened to him.
If you are saying that you didn't want Sanji to encounter females, that's alright.
But that doesn't mean the character got ruined, it just means you don't like the plot that Oda wrote. But Sanji's character's progression was good this chapter whether you like it or not.
