The chief difference between horror fans and science fiction fans lies in why they won't walk backwards. A horror fan won't walk backwards because he knows he'll be knifed by a madman. A science fiction fan won't walk backwards because he knows he'll step on the cat.
There are times when the end justifies the means. But when you build an argument based on a whole series of such times, you may find that you've constructed an entire philosophy of evil." --Luke Skywalker
