So Sanji asks himself the question of which him would Luffy the PK want by his side: the current Sanji who can't fight a woman or the Germa version who would follow any order and be ruthless.
I think Luffy wants Sanji to be whoever he wants. Luffy is all about freedom. As long as Sanji is by his side Luffy has confidence in him to do what needs to be done for his Nakama.
Thoughts?
