No, you misunderstand again. The motive of the torturer is "just for fun." It says nothing about God's motives or knowledge.
You claim there exists an objective moral value; the action 'torturing a child to death just for fun', no evidence to support that, its a position you assert, we tried to get you to come up with a method to establish this in another thread (which ran for a year) and you failed to come up with anything.
Lets hypothetically assume that this OMV exists... this OMV creates a moral obligation on every moral agent to stop this action taking place.
So we than ask why doesn't a good omni god intervene and you claim your god wouldn't allow a child to be tortured to death just for fun.
Now I see what rabbit holes are coming up you will claim 'just for fun' is the motive for the torturer.
So what you are really saying is its wrong for the torturer to allow himself to TACTDJFF but its morally good that your god allows it to happen because gods motive is a good one. However you have previously agreed:-
If morals change according to the moral agent morality is subjective / not objective.
If morals change according to circumstance then the morality is relative / not absolute.
So in all this time using TACTDJFF as an example of objective is categorically wrong because the 'just for fun' part is subjective.
