Consider that she's one of 'the good guys'-- someone who self-reflected on her ambition, saw the 'evil' in hers and other's, called it out publicly, and assumedly regrets hers, and is trying to do better.

Sadly, terrifyingly, for every one of her, there are hundreds who might also self-reflect - but >choose< to be comix-book villains.

And exactly the type to be in power. Explains everything that is fucked up about our world.

She is but in a way that's what makes the book fun. She is very flawed protagonist.
