God operates on a different system of morality. For the sake of this conversation, he doesn't count.

A moral absolute is not defined as something that no-one would ever do. There have been genocides in human history (as we know), and for the purposes of this exercise, what we need to establish is :

"is there a reasonable moral or ethical argument that could be posited to justify any given action?"

If there is, then it is not a moral absolute.

It is, of course, still subjective. There is no ultimate arbiter. Which kind of goes back (loosely) to the OT!
