Counter-thought: Hell is the rejection--and therefore deprivation--of justice.
When the Gospel is preached we are preaching the justice of God, the justice of God that is announced is that the sinner is forgiven: the prisoner is set free and forgiven.
If a person rejects the pardon, rejects the justice of the court, and insists on staying in prison; justice is not meted out, instead justice is being denied.
Hell isn't about justice, hell is what it looks like when someone insists on their injustice and denying justice from God found in forgiveness and mercy.
Justice isn't about reward and punishment, but setting things right, restoration, and righting wrongs. In hell we find the broken un-repaired, the sick unhealed, the sinner remaining in sin. That isn't justice, but the rejection and deprivation of it.
I am not, here, denying the justice of God; but rather saying that to be "in hell" is about denying God's justice. Hell is a prison not for those whom God wants to lock away forever; hell is a prison of the prisoner's own design and intention.
