I have started this thread partly so as not to hijack the one on conscription, but mainly because of a scenario that Facebook showed me. Yes I do read FB mainly because my kids post there.
The FB posting was about a German about to be executed after his Nuremberg trial. He had killed thousands of Jews, some by his own hand, but mainly from by the soldiers under his command. His defense was that he was just following orders, doing what he was directed to do by his superiors and he claimed he could not understand why he was being executed for that.
Okay we don’t accept that as a justification; certainly I don’t and I assume most Dopers don’t either. But what about the person who threw the rope around his neck and dropped the platform? Isn’t he just following orders to kill someone. Well, you argue that he was convicted of murder and should hang. But that is a human law too. Being a Jew was sufficient cause for execution in Nazi Germany. Of course, I understand the difference, but that guy didn’t and he felt he was going to be hanged for obeying what was at that time the law.
I remember the AG of some state (I have forgotten which) who was about to execute someone for whom serious doubt of guilt had arisen. The AG said something like, “The people of [state] have decided that this person be executed and my job is to see to that they are. I don’t care if I were to be presented with absolute proof of their innocence, it is my job to execute them and I will carry it out.” There is something seriously wrong with this, but I cannot quite put my finger on what.
