He’s everyone’s son. Just like every other Chayal. and just like every other chayal, he was responsible for Tohar Haneshek, and just like every other soldier, he was responsible to follow orders and maintain a disciplined posture in all situations.
If he violated either of those responsibilities, which the judges found he did, and which the evidence seems to bear out, there is a disciplinary process that Tzahal has, and like any army must have.
Does that take away from the fact that the terrorist was scum, that killing him in the initial response would/could have been appropriate?
No.
Does that take away from the fact that Azaria acted against protocol because a friend and fellow soldier was injured by this terrorist, or because he saw killing the prone and wounded attacker would amybe deter others?
No.
He’s still everyone’s son even having acted against orders, even in jail, even if he’s done something wrong. And the terrorist is still evil even if he was filmed being killed contrary to discipline and protocol.
