It sucks that his last moment was a feeling of "shame". But I guess I'm projecting here. His resolve was strong. And his mission was fulfilled. Even if we cant shake off regrets, fear, and shame, it's possible to move forward while holding onto those feelings. It might even be a must to have them, as thats exactly the definition of courage. To hold both destructive and constructive feelings, and still be able to exercise what you will. Thus courage brings freedom.
