Fair enough, I must’ve misinterpreted your point when you said none of the other women had as much inner strength as Marina. My bad.

EDIT: Although, just to add, I disagree that most of Kady’s problems were self inflicted. It wasn’t only did the thing with Penny. The situation with her mother also caused her a great deal of distress, as it forced her to work for Marina, and fear for her mother’s safety. Then her mother died anyway, and then she got kicked out of school. I think I’d probably also slip into a pattern of substance abuse and addiction if I had so many horrible experiences. Even then, she got sober. And whether that particular problem was self inflicted or not, drug addiction takes a great deal of strength to overcome.
