One guy to takes it upon himself to kill 50 people. Or a million people take it upon themselves to kill one guy and his family. From the perspective of someone who doesn't care about life, the first case is brave and the second case is cowardice. Sure. From the perspective of someone who does care about life, and doesn't want innocent people blown up by random assholes, the drone strike is justified... if done with 100% accuracy. This is in no way a justification of what happened last week, which was a war crime. But society has an obligation to defend itself against individuals who want to mass-murder and don't care about their own lives or others'.

Just wondering, are you defending suicide bombings?
