That's one thing they teach you when you're in classes to learn Emergency Preparedness, Response and Management. There are times when you're not going to be able to save everyone. You do your best to save as many as you can. It always hurts, no matter who is lost. Be it one or one hundred. But the sad reality is, in most major disasters, and in many minor ones, there are almost always fatalities. All you can do, is do your best and remember that you're not alone.
