Who REALLY deserves forgivness?

I think that the soldier obeying his commanders orders by shooting an unarmed mother and child deserves forgiveness. He's a soldier in the military and its his job to obey his commanders orders. And if he didn't do it depending on what military he's in it could be risking his own life. Like if he didn't do it then they would shoot him. If you were a soldier in this situation you would start talking about your family back home and how much they would miss you if you were dead, and you would almost do anything to get back home alive. Even though i think it's very wrong I still feel the soldier should deserve forgiveness in most cases. Because war is groosome and no young soldier wants to be apart of it.
