It Matters that you Care
Don't let the shock trauma of war blind you into ignorance or apathy, it's meant to keep you in a state of awe, compliance, and helplessness. Rebel against the idea that your opinion doesn't matter. Stand against the orders to kill your fellow man, and love each other instead.
Drop the Ego, let go of the artificial hierarchy you've created to establish your values. It doesn't matter, we're all equal in human worth. Anything that tells you differently is faulty logic.
It matters that you care.
