Souls are fragile things. They can burn, freeze, be food for something else. The simulation is not so much an artificial thing as a computer program would be. Life itself is the simulation. That very simulation protects us from the all the things that seeks to destroy the soul. There are numerous simulations all over the void, but traveling between them is suicide. Etherial winds can carry souls between simulations. but they are quite unreliable. The Simulation requires soul energy to function however. Upon death of a vessel housing a soul a bit is scraped off, not enough to harm the core of the soul but enough to weaken it and thus allow it to go back into a vessel to live and regenerate the fragment that was scraped off to power the machine of Samsara. Safer pockets exist in the upper planes of existence but they are occupied.
Who controls this particular simulation and what they do with the excess soul energy is anyone's guess.
