"Both ideas are taken on faith, they may both be true, they may neither be true." They aren't equally true or untrue. There's more evidence cryonics will work than that afterlife-capable souls are real. The question is whether it's enough to be worth spending money on. I like your idea about supernatural cryonics fiction though. I've considered writing stories like that myself. It doesn't have to be unpleasant for the souls; perhaps they are sitting in a camp outside the gates of heaven or hell, communicating with each other and sharing ideas. They could perhaps later carry messages back to the mortal world, granting empirical proof of the afterlife as soon as they are reanimated.
