Not even enough for a campaign framework, but it's something I thought of recently that could be interesting for fictional exploration:

When someone is brought back from the brink of death, they often have a life-changing epiphany. What if that's because they come back with a soul, not necessarily the one they left with? Since most people (living and dead) are neither saints nor fiends, this usually causes minor changes in outlook easily brushed off as being scared straight, realizing one has but one life to live, etc. If the soul is mostly subconscious, and the conscious (biophysical) mind is free to act upon or fight the urges and nature of the soul, this could be terrifying, especially to the poor fellow who has suddenly wound up with the soul of a mass murderer.
