Are you trying to troll me? I already said that when it comes to the OOO God I find the sole concept of the greatest good contradictory. So yes, obviously, I think your argument is futile against the OOO god, the greatest, infinite being. The greatest being is the one that decides what prevents what and what causes what. If it doesn’t do it, it’s not the greatest being since it means there’s a higher being than it which limits its actions.
EDIT: To avoid confusing you, I do think your argument is logically impossible (that’s what I meant by futile) in relation to the OOO god.
