tag yourself i'm kankri's madonna-whore complex
He really is slut shaming the Madonna huh. Jokes!
That offers a good rationale for why when Latula jokes about being ‘untouchable’ Kankri actually gets really worked up about the (perceived) insinuation that he wanted to touch her. If you compare that with how he insults Porrim for basically being touched /too much/, you can gather that Kankri’s refusal to actually pursue Latula comes from the idea that if he actually touched Latula, she would become a dirty, fallen woman like Porrim. So he has to abstain!
This links up nicely with the subsequent reflections on silence – keeping the girl on a pedestal, keeping the angels in heaven, keeping the child in the womb, keeping your thoughts to yourself. Preserving sanctity by refusing the precious thing interaction with the world.
