Understand please, I support the death penalty and I don't want this thread to degenerate into a pro/con debate on the subject. However, 277 were executed but thousands of German soldiers and SS troops who participated in these atrocities escaped judgement for years. I agree with
@Alparen that there is always a danger of the innocent perishing. That is one reason I believe the penalty must be judiciously used at best. But when you have someone like Himmler or Bormann or Speer whose guilt is proved beyond any conceivable doubt I feel there needs to be some justice that speaks to the enormity of their crime. Should all those involved in the Showa be held accountable? If we were to do that we would have to execute a sizable portion of the German population. As pointed out in the book
Hitler's Willing Executioners by Daniel Goldhagen there were very few "innocents" in Germany. A good portion of the population either participated directly or indirectly in the Holocaust. Example: the train conductors, the bureaucrats who aided in the paperwork, I could go on.
My point is, most of the German population was guilty of this crime to one extent or another. (Note I say most not all) All of them should not stand trial by any means. But the leadership that made the decisions that led to this should be held to strict account for what they did.
