I've probably talked abt this before, and I can't go fully into depth rn bc I really need to like. Eat breakfast. But Aphra ajshfjejsjf
Like just. The way that her fatal flaw I feel isn't her egoism or greed or impulsivity or fear of commitment or lack of consistent morals. Her fatal flaw is her belief that she can't change any of those things. She's convinced herself that she's incapable of change or improvement in order to absolve herself of the guilt stemming from her awful actions. She's so certain that she's unfixably bad + doomed to die alone that she rarely tries to actually become better or genuinely connect and stay with those around her.
And part of the problem is these beliefs are reinforced by the people around her, for various reasons (especially in her 2016 run). Sana told her something like "its not your fault you were born broken" or smthg, bc Sana also wasn't ready to reckon with the fact that Aphra has free will but used it to hurt her. Triple Zero for a while keeps trying to make aphra believe she is like him (very evil and cruel) bc he wants another friend in his evilness. Even as a kid, Aphra's mom told her that some people(specifically referring to Aphra's father) are just "wired different" and are so fixated on specific things and end up bringing down trouble on themselves and everyone around them. All these things and potentially more I've forgotten keep reinforcing to Aphra that she's stuck the way she is, that there is no point making the effort to change, and that everyone who loves her will just need to overlook her problems instead of trying to help or excepting better.
Basically Aphra's issue is she needs to take ownership of her actions and the harm she's caused and acknowledge that she is capable of being better. And then there's the whole exteemely difficult mess of actually wanting and trying to do better. But yeah, she needs to know she's capable of it to even start.
