Everyone fears death.Anyone that doesn't is either brainwashed,lying or delusional.
You can risk your life and still be scared of death,so don't pull the "brave soldier" argument on me.
In fact,how much are you willing to bet when one of those fearless types die in battle,they suddenly cry for their mothers and ask Something to keep them alive?
You cannot say that you are leaving your material form and going to a great unknown no man can observe,rationalize or understand,or not be afraid.We,as humans,are afraid of the unknown,so when one of life's greatest mysteries rears its head,no one is stoic.
