A character who ethically believes in a natural order (like an honor code or natural caste system) would be lawful regardless of whether or not he does that he pleases; lawful describes his ethical belief system, not his behavior. Now, how exactly his ethical beliefs play into what it is he pleases doing and how he pleases doing it is a different matter.

On the moral (good/evil) scale, it's a neutral character who would kill one person to protect another. Generally, the morally neutral characters sacrifice or kill for the sake of themselves or the people they have relevant connections with (love, debt, etc). For example, depending on his ethics, he might have general disinterest in or even impulses against harming the innocent, but on the flip side, lack the commitment or motivation to turn around and make sacrifices to protect or help others the way "good" does.
