Very good episode even if I can't understand the compulsions related in the story myself.  In a sense it made me sad to think of the people in the world that are really like the people in this story, but hopefully they find someone or something to help them out of their low state.  I did wonder how many of the deaths were actually NOT done by the members but by the assistant - after all, if they have problems killing themselves how could they kill another person?  You'd think they might get so upset after killing another person that they would follow through with themselves, but I'm not a psychologist nor do I play one on TV so I'm just guessing.
