Just wanted to point out that while Jasnah dismisses romantic connections with a man, this doesn't in any way mean she is asexual. She's precisely the kind of person who'd see sex for what it is, and having no issues having sexual relations with a man without letting that mean she'll marry him.
And I think Jasnah's change when she became an adolescent may simply be because she figured out that her mother did not love her father. I don't think she hates Navani, but she probably figured out that her mother married the elder brother out of political expediency. And I think that explains both her disdain for getting tied down to a man (especially one you've never met) and her comment comparing using the beauty of your face to get a man being the same as a man using his muscles to force a woman.
She is the kind of woman most men in a place like Alethkar would be turned off by. In fact, I distinctly remember some lord or prince in WoR making a disparaging statement about her along those lines. I think that's something Jasnah the adolescent would have sensed too, and that would have made her disdain the men around her even more.
And I agree she isn't a very good candidate for a sociopath. The quote about Taravingian is telling. She's troubled that men who are violent and aggressive to gain success are viewed as the best men. A sociopath would have much less trouble with that.
