As someone from the duke's side, we know that he is trustworthy, however, he did grow up in a society where women are treated unequally, and is socially conditioned to do it. Although I think that his attitude is wrong, I don't think he meant to have any malicious intentions towards her but instead confusion between what he has been taught and engrained in him with what is present in him.
I quite like Juro because he's character is very consistent yet still developing as the story goes - in fact he can already be considered different in the sense that whilst holding these beliefs/values towards women, he acknowledges Ebony (n ofc the staffs in the house)
There is so many instances where we question why someone can have views that are totally against ours which we believe to be right - you know who/when they are.
The next chapter will definitely be a good one as I believe that we will see both sides of the argument/society, which I think is what the theme of the story is.
