Even if God exists, and even if Torah is true, there is STILL no objective morality

Funny that.

But clearly no one knows the objective morality. Even Chareidim who believe 100% in God and Torah still don't know the objective morality, since in any given situation you have to use your judgement to decide what to do, or at least decide who to pasken like, and whether to be maykil or machmir. True, you can believe that the Torah guides you generally, but at the end of the day the individual or the posek has to use their judgement. So it's always going to be subjective.

And in fact morality MUST be subjective (at least from our perspective), since if it truly was objective, and there truly was a demand on you to follow the objective morality, then God by definition would be immoral, for making a moral demand on you, but then not telling you exactly what to do. Since God can't be immoral, therefore it must be that God (assuming He exists and cares) requires that we figure out our own subjective morality.
