It actually
has crossed her mind in a fashion, in her reminiscences of Pirasha, who was her 'mentor' in her more youthful days as a harlot, and also a terrifying reminder of what lay in store for her. But not in a thematic way, which is quite important.
I do think you're judging her (or me

) prematurely. From the standpoint of the destination, the journey always seems easier. But since I'm not a woman, I realize this is more a work of imagination for me than you, so all I can really do is try to explain the way I see her character.
First, she suffers from depression. One of the principles I took for all my characters can be summarized as 'That which does not kill makes one
stranger.' The typical human response to sustained stress is far, far more likely to be pathological than redemptive. I wanted to bring psychological realism to my characters - as far as I'm concerned it makes them much more interesting. (I probably receive more complaints on this point "too much whining," "no likable characters," and so on, than any other, but this simply tells me that my books are reaching readers who haven't learned to appreciate characterization like this - which for me is good thing). This is just to say she suffers more than her fair share of self-hatred.
Second, there's what I call 'ignorance squared.' Since people don't know what they don't know, it doesn't even exist for them. Just try to think what the next great insight will be, and you realize quickly that it's impossible, even though 50 years from now, it could very well seem as obvious as 'human rights.'
Third, there's what I think of as the 'Labyrinth.' All the characters, especially those close to Kellhus, find themselves in a spiritual labyrinth they must find their way through. Esmenet's labyrinth becomes very tricky indeed, and it's just
starting in chapter five of TWP. I don't know if she's going to go where you want her to or not, but either way, her journey is just beginning.
Self-hatred. Self-denial. Self-identification through male desire. You name it. She has a lot of monkeys to throw off her back. I'm not sure it's as straightforward as you're suggesting. As it stands, her world is squared by her ignorance - but that's changing, gradually.
Back in my teaching days I used to spend a week, sometimes more, on Cosmo and Maxim, comparing and contrasting them, and interpreting them in cultural critical terms. I'd use it as a stark example of how patriarchalism is alive and well in post-feminist culture, showing them how the overwhleming tendency in Maxim is to show men how to
deceive women into desiring them, the overwhelming tendency in Cosmo is to show women how to
remake themselves so that men will desire them.
Creepy, creepy stuff.
