No, because he chose to be the "outcast" and leave his teammates looking like shit when they collectively decided to stay in the tunnel. You think Rapistburger or Chickillo there with their hands over their heart wouldn't have wanted to show their respects as well? He could've stayed a few feet back with his mates and been just as honorable. I don't think you understand the camaraderie football players have. Yes, its not as comparable as your battle buddies, but its not just some "sports team" shit relationship you just threw out.
Again, as I said, he served 3 tours, so you can't fault him for doing what he did. I also can't fault his teammates, who stood a mere 10 feet behind him, giving him shit for it.
