[St_Thomas_Aquinas]

Hell is just because it is what the damned choose: their will over God's, or eternal separation from God.

(Justice isn't what God says is just, otherwise God would be indifferent to good and evil, or could even will good and evil. That is what the Muslims believe. Since God is Goodness Itself, He cannot will evil. God only allows evil, so that greater good may come.)

("Justice isn't what God says is just, otherwise God would be indifferent to good and evil, or could even will good and evil."

Sorry but I'm not connecting those dots at all. How can anything be just apart from God declaring it so? How can anything be right or wrong apart from God declaring it so? God is the only source of the ethical normative.

[DManA]

No one would freely choose endless agony. It’s not reasonable to think this and it’s not Biblical either.
