Q: Why did you kill your neighbor?:
  A: Curiousity

  That perhaps is about the most concise possible answer, next to
  "Because."; but Curiosity is even better. *I* think you should
  win this. Then again, I'm not sure if Curiosity has a place
  within Philosophical dialogue but if it doesn't, it should. Were
  I a judge and that was the answer, I would need no further
  evidence. The need to keep the person out of society would be
  clear and with one further answer, "What were you curious
  about?" that would determine which University department I would
  make him Chair of... for there is no better way to be removed
  from society than to Chair a Department at University, with the
  one equivalent position that of a political role.
