Lawful is not morally superior to Neutral (or to Chaotic).

I think she's Lawful. She's addicted to hierarchies, with her at the top. She thinks it is an immoral thing not to enslave people. She talks about how she doesn't do things because they're illegal as if "illegal" means "immoral", and it is clear that if something's technically legal, she sees no problem with it at all. She thinks that because she has power, she is morally superior to those without it.
