She watches them get slaughtered? She’s the only character who acts, though. She saves one of them and kills it. But… wouldn’t it be more traditionally feminine if she DID stay on the sidelines? Isn’t fighting a masculine trait?

Again I’m not sure what you mean by the compassion comment. She’s repeatedly compassionate throughout the series. In the mountains she is WITH the party, and she is it’s leader. Making a decision and showing agency is what a leader is supposed to do, whether they’re matriarchal or patriarchal.

She shows a good deal of compassion towards the people she she is fighting to save by tackling a threat that she knows still exists. She rides for days on end to save a man she believes to be a rightful king and leader to a suffering people.
