If you've ever been grilling a sausage and had it burst spraying hot liquid sausage fat all across your tender, trembling face and shirtless torso it becomes less of a debate and more of a safety precaution.
Your great sacrifice was not in vain. It bought time. If nothing else, even if it all falls now, it bought this world thousands of years of time. That's not in vain. That's not insufficient. Do not dread your end, for you gave us our chance to be, and now it's our turn to fight.
