It's not better to just admit that it was a dropped plot point?
Oda put it in a single page, didn't like how it ended up and decided that it was better for Sanji to keep being normal and hating those things. It make way more sense than what you writing.
All I wrote for the page is that he shows anger in the image.

For the NON CANON ANIME FILLER Toei wrote him brainwashed.
