justice is a subjective thing.so there isn't a thing as a perfect justice and the many arguments here proves that.
Justice is subjective to us because we are limited by wisdom, selfishness (i.e. "I am right no matter what"), and all the things that are and we are not aware of (what exactly has happened, one's feelings, thoughts, etc.).
So, from our position, it may be subjective. But for one that doesn't have these limitations, I don't think justice is a problem.
i can state now part of the limits:time travel (we could only be able to travel to alternate universes.sure not in the 200 years limit).
space travel: we wouldn't be able to cross the speed of light.
life an d death: we would be able to reanimate the body but not the personality of the person.
1. are you sure that alternate universes exist?
2. if you talk about the reanimation of that cell, from what I've read, it was no reanimation, but changing the DNA. Do I know wrong? By the way, if the body would become reanimated, why the personality not? you mean, that is not in the body, or what?
3. what about those limitations that would not allow us to become as God? do you know any? (because that was the subject)
