Would you kill to save a life? Would you kill to prove you're right?

A glimmer of an idea teases my muse and I marvel at its source--a 30 Seconds to Mars song. I don't know if there's a story behind it or it's just an idle fragment of bought that could be built upon. I put it here so I'd be held accountable for it. Violent? Maybe. But there's a hint of truth there, a longing for justice, propelling someone headlong into something they could not possibly understand. I don't know why any of these things would be happening, but that's part of the magic of creation, isn't it?
