In Greek mythology, there are two options of Afterlife where people's soul will live in after they die. The first option is the Asphodel Meadows, which is a large meadow of nothingness where everyone loses their memory, but they receive neither punishment nor rewards regardless of the amount of good or bad things they did during their lives. The second option is the Court of Judgment, where people will be judged based on their actions. If they do more good than bad, they will receive the reward of living in the Elysium, the Greek parallel of heaven; otherwise, they're going to the Fields of Punishment, where they are punished for horrible deeds they did in life, using a variety of horrible torturous methods. For the purpose of this debate, the judgment is absolutely fair and objective.
A person chooses whether they want to go to the Asphodel or the Court of Judgment before they are born into the world; the choice is binding and cannot be changed. Once they are born, they immediately forget the choice that they made.
