Okay, huge caveat here: I am extremely enamored of my concept of free will and absolutely reject the idea that the world is pre-ordained. If there were no such thing as free will, I would create it if heaven and earth were to fall by the action. Enough hyperbole.
Imagine that the universe is not only preordained, but it is already a finished object. That time appears to flow from our dimension, but is solid and finished from the next one up. It could be a finished object or a giant computerized simulation. Doesn't matter.
What if there was a 'being' (spirit, essence, soul, whatever) for each thing in this simulation (would beings include only the sentient? Only the living? Only the discrete objects? Or each and every particle and quanta of energy? don't know.)?
What if destiny was that each and every essence would inhabit each and every thing. They could not change or influence the lives, but only experience them. So everyone would be the first human and the last human, a shark and a Yersina pestis germ. Everyone of us would be killers... and every one of us would also be victims. But not just any victims, our own victims.
It would make an interesting faith. A world of perfect justice, because everyone would experience everything. It has an ethical system built in because even though we can't change the scripts (and who is to say that the program can't be shifted?) the incentive for being good to others is that you will eventually, be those others.
Just a thought. I like my free will and I've known too many victims to be comfortable with an idea of abstract justice (though justice is a pretty abstract concept...) so if this new faith arose, I wouldn't be among the converts. But I think it could garner some.
