Case study, feels like school

I assume you know the answer or you wouldn't be asking?
I assume these 50 people don't run a prison cause that would detract too much from their productive endeavors? In that case I don't know, problem is too far removed from any common scenario I'm familiar with.
Or they do have a prison, in which case they put him in there, probably for life, and now 48 people have to decide how to redistribute their responsibilities. Since the loss of productive labor is proportional to the loss in population, that should be possible.
Furthermore, I would like the state in this 50 person country to offer therapy to those afflicted. That may not heal them completely, but it might help them rebuild their lives.
