Sure. Lawful Neutral. Or Lawful Evil. Not Lawful Good.
Lawful evil quite probably.
By declaring genocide, murder and rape (and the people who engage in those practices) as being evil, you're not losing any nuance. It's a self evident statement. If you declare them as anything else than evil, you're forming a disconnect (or making a personal moral statement that is... concerning).
The murderers, rapists and genocidal monsters probably think they're good, and doing it for a good reason.
They just arent. For obvious reasons.
