It should be pointed out that our death is not a punishment for Adam's transgression but a consequence imposed by God for Adam's choice. Man's fall was prepared with the blessings that come with the resurrection and the promise of immortality and greater opportunity for spiritual development.
If there is no opposition to choose from then there is no agency. This is how we know if we have faith in Christ or not. By our choices in life. These things contribute to our test in life or the trial of our faith. God teaches us the good and our eternal worth through divine commandments and Satan tries to gain followers through falsehoods, deceit and selfish pleasures. This is why salvation is an unconditional gift of grace and exaltation is by grace after all that we can do.
If deity were in fact able to save individuals in such a fashion then creation would not really be necessary because choice would not be necessary except for a single act. If such a doctrine were true then creation would not be necessary since it would indicate that God has power to save without requiring the individual to be responsible for the rest of their life. If the individual does not need to be responsible for their acts then no creation is necessary. God could have just created the persons in a saved condition in the first place.
The parable of the talents and other passages of scripture explain this principle. Those who do nothing to obey God will receive the free gift of the resurrection and whatever eternal glory his mercy will provide. Those who love and serve God will be prepared to receive of the most glorious kingdoms prepared for their eternal life and exaltation.
