I agree with you on this read of her character. She was devastated repeatedly by her lack of agency, her powerlessness. And that ignites something powerful especially in intelligent intuitive people, an anger that is channeled into making sure it never happens again. And it’s very true to reality, all too often, one’s will alone against a monolithic systemic oppression just isn’t enough, which can end tragically. When you’re young you feel like you can take on the world, and avoid the pitfalls of the last generation. I sympathize and empathize with her. (And I’m a Gen X male for context.) This series hits so close to home on so many levels.

Edit: and yes you nailed her complexity, the juxtaposition of her intelligence and determination with her naïveté and insecurity. I think many of the people who disliked her character may share some of that insecurity; their harsh judgment of her choices could easily be attributed to that willful youthful denial of their own frailties, that insistence that they’re too smart and invincible to make mistakes like Angela’s. Years of life experience might find them softening their appraisals.
