[Serious] What God's justification for eternal torment?

[Angrboda]

That's one definition of immoral, but even that implicitly recognizes that such standards are intended to reflect objective moral truths.

The definition explicitly fails to use the word truth and instead uses the words "accepted standards".

What is accepted changes over the time and very well may not be truth at any point.

You're equivocating. If what is moral is defined by accepted standards, then the class of true moral propositions ("truth") is defined by those accepted standards. You're trying to appeal to a different definition of moral truth, an objective one, after having adopted this first definition. That's an error. Either what is morally true is what accords with accepted standards, or it is not; you can't have it both ways.
