I think she is taking revenge on her emperor because, she’s pretending to still be doing his dirty work, but in actuality she’s trying to find the cause of her fathers death. She doesn’t hate the prince really, IMO, I think she just kinda fears him in someway cuz he is the person who ordered for her execution even though she is at fault for it too.
