Connection between Pat Tillman and the Sniper

After reading both the story and the article I have tons of connections. Not only that they were both in war against their enemies, but one killed his brother, and one was killed by his brothers. After killing his very own brother the sniper must have felt really ashamed and guilty. Even though they were related they were against each other. They did not have any connections or communication between themselves, and they must have been misery because of that. In the real life situation of Pat Tillman, he did not kill his own brothers. Instead, he was killed by his own brothers. The people who killed him must be really guilty. I feel sorry for Pat Tillman, who gloriously left this world.
