If I could just throw out a few ideas, you are really close to a kernel of an idea I had for a short story. Back in the day when leprosy ad the black plague were going around, people with leprosy were in a unique social situation, in that they were considered to be victims of their illness due to some sin against God. However, leprosy was their punishment, not hell. They called it the "divine disease" because while such people were cursed, they were also paying their penance simultaneously. Anyways, such people were segregated into camps, some of which were quite large, positioned outside of major cities all across Europe. Such an environment would be so suited for a story, and could make for great RP possibilities. If you wanted to,characters could explore the whole "good vs. evil" morality thing. I mean, if God has blasted people all around them with flesh-rotting or quick-and-sure-death disease, they have to be wondering why: why are my neighbors dead, why am I alive, WTF God, you know, that kinda' thing.
Anyways, not terribly interested, but the title is perfect, really caught my eye, just wanted to make a suggestion.
