I read it in the novel and earlier chapters of this manhwa that slaves in the empire are criminals that did something wrong and they are slaves until they paid their crimes off, so slaves are really the lowest of people there, and the fact that Trashta is a runaway slaves made her worse than those slaves
I know Rashta is garbage but as an antagonist I find her compelling, more than anything I feel sorry for her. Maybe later in the manga they'll tackle the issue of why there's slavery in the east empire at all. I think it would be an interesting direction to take since slavery seems to be pretty common in this specific genre of fantasy.
