"Max, this won't fix anything," Sam said.
"You're right," Max agreed. Nobody had ever cared about him. His mother had died and left him with his abusive father. His father and uncle hated him so much that they used him as a punching bag. His stepmother pretended to care about him, but when push came to shove (literally), she did nothing.
With his mind he swung the gun to his face, and still looking at Sam, he pulled the trigger. Looking in Sam's eyes, in that last instant, he realized he was wrong. Someone did care about him after all.
