Free will was a hot topic this morning. I was sitting in the Springfield, MO airport watching the news accounts of an American soldier’s murderous rampage through an Afghan village when the fellow next to me mutter, “poor bastard.” I glanced over at him and he took it as a rebuke. “I’m not saying I don’t feel bad for the people he killed and their families, I’m only saying that we should have compassion on the guy: four tours in Iraq and Afghanistan, the guy just snapped. The system killed those people as much as this sergeant did.”
