The Masterful Plan of the Pale

Everything is going so well that I almost feel like I'm cheating, for real. The harmony of it all made it seem like I was just mind-controlling to do precisely what I want and just go on with it till the dungeon ride is done. Really, the plan is simple: I want these three messy characters—the policeman, the salesman, and the nurse—to kill each other hopefully soon once we leave this overly disgusting and 100% dark hallway. That's just it, really, since explaining more of what I have in mind will only ruin the fun of the dungeon for you! However, I am confident that I can pull this off somehow and will leave this place knowing that I did not even do or said anything to make these three people kill themselves just because I showed them a diamond rosary. It would be phenomenal!
