Every human being has a basic instinct to help each other out. If a hiker gets lost in the mountains, people coordinate a search. If an earthquake levels the city, people all over the world send emergency supplies. This instinct is found in every culture without exception.
I am the one who runs from both the living and the dead, hunted by scavengers, haunted by those I could not protect. So I exist in this wasteland. A man reduced to a single instinct: survive.
