I am not opposed to that being her prospective character arc but she’s not portrayed that way. There’s nothing to make us like her and from the storytelling and craft perspective there should be. We should at least see her questioning herself. She’s not presented as a cautionary tale. She’s presented as a strong woman who has to deal with domineering men. Even that would be a compelling story line. But again we don’t have any way to sympathize with her. She treats every other character except her brother in the intro with contempt. All she does is try to prove to the haters that they don’t understand her and she’s gonna do what she knows is right regardless of any warnings.
Isn’t this just because we, the viewers, know that she is right given the whole Sauron is the big bad in Lord of the Rings? We are suppose to appreciate her focus and refusal to give up given that we know she will be ultimately vindicated.
