Of course it's possible to say someone is an asshole without knowing the "full consequences."
How can you judge an action without knowing all that led to it and all that will happen because of it?
If you have the power to stop 1000 people from dying, then you tell them to do something and let them die, you're an asshole.
Sure, if i (a human) were to do it, I would be an asshole but we can't judge an entity that is infinite with the same logic.
If he doesn't want to be called an asshole, let him defend himself. Or is he not omnipotent enough to do that and you have to do it for him based on your own unprovable claims?
I don't think he cares what you think considering you do not have the same knowledge as him (we all are created and he is the creator). But even if he were to defend, based on your request, there are multiple assumptions you made. Such as he needs to show up and talk in front of you, when it could be that me agruing here is the manifestation of him defending himself.
That cat is actually an assassin, when he lays out his plan, he has to check if it worked or not. Beware!
