Hence why it's so interesting. They are obsessed with honor of the family name and appearances but, just below the surface, they are engaged in the same Shakesperian/Game of Thrones treachery as everyone else. I will say that the way they treated courtesans was more enlightened and mature than us now. Courtesans were seen as artisans. Even if the person, themselves, wasn't fully respected, their position in society certainly was.
But, I guess, along with that structure comes dictatorship, monarchy and the inability for any average person to ascend in that society without direct help from the feudal lords above them. Not ideal.
