The fact that a terrorist is loyal to his terrorist brothers and resisting arrest might impress you. It doesn't impress me. I guess you were also impressed by Dzhokhar Tsarnaev putting up a fight before being arrested and after killing and injuring hundreds of  innocents. There was no valour in Khadr fighting the attacking yanks - he did so to survive: there was no way out. Look up valour in the dictionary.

Child or not at that time he is a murderer.
