Imagine a world where any human suffering caused by other humans creates demons in the world. A cruel word may spawn a mischievous sprite. A murder may create a prowler that would crawl the streets and kill a dozen more people before stopped. Battlefields become corrupted lands uninhabitable for centuries.
This is not a 1 to 1 relationship. Maybe 1 to 10, or 1 to 100. Things add up in locations. Maybe a theater would be haunted by one harmless spirit of "not laughing at jokes".. On the other hand places like a prison would be death traps where demons slither behind every corner.
It would lead that the culture would have no tolerance for any such crimes. It would be unthinkable to commit even small crimes with a victim as the consequences could be dire.
But how would this culture enforce its laws? What would you do with a murderer or a thief if anything bad done to them would spawn demons from their grief or their families'?
The demons are created by the evil in the hearts of men, not by the actions. This is why natural events, accidents done by humans, and the demons don't usually contribute to the cycle.
This may mean that if the judge, the jurors, and the executioner all have pure hearts and take no pleasure in the act of punishing the guilty there could be no consequences. Unfortunately that's not how real life works, and no one could ever ensure that.
