I guess the question is what qualifies Abner to judge kodiacman? If we are equal then our authority is equal and we have no basis for calling one action evil or good.
While you are equal, the societies to which you belong are different. Abner will judge kodiacman by the standards of the educated atheist society of which he is a part. Kodiacman may very well say that God does not approve of the educated atheist society, or at least the atheist part, and in effect say 'Throw Abner to the wolves.' Abner will probably like Brer Rabbit say 'Don't throw me into that briar patch full of atheist chemists.' And you both will walk away feeling virtuous and filled with righteousness for making the correct moral judgment."
