Okay...
Terrorists actually believe God wants them to do what they do. They don't do it because they think they're evil. They do it because they think we're evil.
So what do YOU think? Is there no objective ground at all to decide these things?
Convince me that dropping a bomb on a house with five terrorist leaders and a dozen civilians (who, apparently, have no idea who strange men in their house are) is morally equivalent to flying an airliner full of passengers into a giant office building.
