I feel like when your job is working at the massacre factory either you're some degree of sociopathic going in or it's something you develop as a consequence of attempting to compartmentalize what you do at the massacre factory

the motivations for why a human woman in a human-supremacist Empire would be attracted and motivated to perpetuating that order without some simmering psychiatric condition influencing her decisions.

Why isn't "she's a psychopath" a good answer here tho? I doubt that the nazi party for example didn't have a very increased rate of psychopaths in their ranks.

Andor doesnt do the whole "imperial core"/"white woman tears", its not really a story about intersectional fight against imperialism, more like anti-fash. Thats why most characters that die arent white. Andor in general has not great writing for its female characters. Dedra was raised by the empire and there is nothing else to her.
