There is more than one way to kill somebody. I suggest construct a situation where the PC chooses between adulation and death. The precursor of this setup is the PCs get hired in a series of events that make them famous in the town. The first event could be to rescue a young doe eyed girl who was recently taken as the main feast at a vampire ball. When the PCs return the girl they are treated like heroes. The next event is lifting a blight being caused by a twisted druid on the local crops. Again the PC are becoming more and more famous. They drink for free in town are mobbed when they enter town with people trying to shake their hands and asking for autographs. Finally, have the PCs quest to find and restore the ancient statue of the town patron deity that was looted in an orc raid two hundred years ago. After the PCs return the statue townsfolk trust the PCs beyond reproach. They will gladly loan money, let the PCs stay for free, buy back loot at cost, or marry their sons and daughter to the heroes.
This happiness continues until cultists kidnap the original doe eyed girl and a hundred other townsfolk. The climax of the setting is an un-winnable situation. After defeating the cultists – the townsfolk are shackled to pillars and the central area has a ball of magic descending and will momentarily hit the altar and the painstakingly prepared doe eyed girl the central part of the ritual. The ball of infernal magic will eat the flesh of one person. The nearest PC and the only one who can reach the ball is the DM PC. Does he kill his reputation or does he sacrifice his flesh and save the townsfolk yet again?
Either way the hero of the town dies.
