In the movie Repeaters, three dream characters are stuck in a repeating one-day time loop. Two of them learn to forgive and break out of the loop. The third won't shift his mind and so continues to repeat. There is no punishment, just a repeated opportunity. Jason points out that the "Choose Once Again" section of ACIM offers you the choice of being your brother's savior or holding him in hell. When you do not choose with weakness, you have the strength of Christ.
