I am always surprised when I see victims fraternizing with their executioners. That is very unjust. The executioner deserves the same treatment type that gave to the victims.
Nobody is forced to be a soldier. The guy chooses to be a soldier. No soldier is forced to accomplish orders. He can disobey his commander or even to take out the pistol and to execute his commander.
This American soldier, that did affirm to be sorry for the treatment that gave to their former-prisoners in Guantanamo, he wants to appease the bad conscience. He didn't have courage of rebelling in the appropriate moment. Why does he deserve now to be admired?
