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

[Gwaithmir]

Everyone determines by choice if they want to have eternity with connection or separation from God.
God’s nature doesn’t allow for torture, torment; if anyone experiences that, it's entirely self-imposed. ‘Burn' is symbolic of what separation from God is liken to.*
*2 Thess 1:9 These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power.

“If this is your God, he’s not very impressive. He has so many psychological problems; he’s so insecure. He demands worship every seven days. He goes out and creates faulty humans and then blames them for his own mistakes. He’s a pretty poor excuse for a Supreme Being.” (Gene Roddenberry)

Incidentally, your "Atheist Credo" is bunk. Atheism is about the existence or non-existence of gods. It has nothing to do with cosmology.
