[Gymnfacymoota]

I don't think it is a question of a "Just" vs "unjust" law.

If you drop a hammer in a positive gravity enviroment it will fall to the ground. Karma, in my understanding, is simply another of the laws of the universe and not subject to what we sometimes think of as conceptual moral values. We are at all times the sum total of our Karma in the same way thay any other object is the sum total of all the forces that have acted on it
