Extend the Story - Add a Room

You strike the man in the face with your mighty fist. The blow goes straight through the man as he flickers and disappears. With no transition at all, you instantly find yourself at the bottom of a spherical room, lined completely with monitors depicting the face of the man you just attempted to murder. The faces all speak at once:

"By choosing to destroy me, you have made a choice about your destiny. That decision is for the instantaneous and complete nullification of yourself and the world you know. What do you say to that, jerk?"

"Whoa."
