The perfect afterlife would have to have perfect people in it, or it would not be perfect. Since the people who would be in the afterlife are not perfect now, they would have to be changed somehow.
There are people with serious medical conditions that define their entire lives, like those kids with no immune system who had to live in a bubble. It is hard to imagine someone more deserving of a great afterlife! http://en.wikipedia.org/wiki/David_Vetter
But in the afterlife they would have to learn an entirely different way of being, where they can go places and touch people and eat whatever they want. Would they just be magically adjusted to not being in the bubble anymore? If so, that is a pretty major change.
Those two people who do not want to speak to each other on earth
would somehow have to forget their differences or whatever to be able to speak to each other in the afterlife.That definitely implies that people would be very different in the afterlife, without what we consider normal human emotions.
No boredom, no anger, no greed, no pettiness, no jealousy, no allergies, no bad childhood abuse memories, no ambition, no sexual desires.
It seems to me that each person would have to be in a separate after life, each populated by beings like the androids in Westworld.
As much as I like Yul Brynner.....
Doesn't all that make you think people would have to be changed rather dramatically for the afterlife? Even if you eliminated all disease, war and death. Otherwise, the afterlife would just be earth all over again, same people but with higher property values.
