For an Imperial, Dedra is
surprisingly popular in STAR WARS fandom. It's because she (and other Imps) were written as people first, with their own compelling motivations and plot lines. "Andor" truly showed how everyday people can be accessories to fascists even when they don't think they are. They think they're doing the right thing and by the time they realise they are oppressing others (do they ever realise?) they're so far in that this seems normal.
Where Dedra stood out is that she is the only woman we've seen with this rank, or level of power. High-ranking women in the Empire are few and far between.
