This inspiring quote comes from Jim Thompson's last story.
"Would they do it?" I said. "How can you be sure they would, Mr. Krutz? Have you ever thought about the potential in a crusade for not doing the things that someone else would do if you didn't?"
A few seconds later, the narrator brutally murders Mr. Krutz. OK--in light of later developments, maybe it's not so inspiring. You have to admit, 'though, that sentence "Have you ever thought..." is pretty good. ---o0o---
