ok to recap,
- amelia became hunted by nobles for saving her sister, who was literally kidnapped and raped by nobles
- her hunter comrades, who were the only people she could rely on, deserted her
- nobody else helped them escape the country or find refuge
- amelia still managed to somehow scrape by and provide for her and her sister despite being fugitives
Amelia was a total badass for being able to rescue her sister, evade capture and execution by nobles, and still manage to survive despite being a young, uneducated woman with no family or friends and nobody to help her. If I were in her situation I would feel helpless and powerless, I probably wouldn't have been able to save my sister in the first place. But I know I would hate nobles and the corrupt power structures they perpetuate. And if my sister were so traumatized by that pervasive system that she convinced me to end her life I wouldn't know where my emotions would drain but to dark and unfathomable depths.
Amelia becoming a devil and killing civilians is reactionary and cathartic, it is definitely not moral (she doesn't even try to justify it) nor is it a compelling theory of change. Perhaps it is partially an attempt to obliterate her own identity as a complacent civilian who was unable to challenge the status quo and was even complicit in some of its horrors, culminating in the assisted suicide of her sister. Most of those civilians never fought back against the injustices or inequalities in their society (such behavior is even discouraged in our world), and they ultimately met even their own death with no agency. It is a twisted revelation that to me is in many ways a penetrating indictment on what their (and our own) society values and prioritizes.
