Which is a lying accusation; he was the poster child of free choice in this affair.
After WWII there were a lot of middle aged Germans who did have direct knowledge and parts in the “final solution” who were let go with minimal punishment. For example, Google the Wannsee conference and see how many of those men, who were in at the start of the holocaust who were let go with little to no punishment.
Fact was with the cold war, an awful lot of folks with dirty hands were de-Nazified, some went on to serve in the West German Government.
They are all dead now.
Now as my family had some association with the german army I can tell you about the culpability of the young medic who was 22 in 1945 and likely drafted around 1940. The way it worked as a “soldat” was you could question an order if you thought it illegal or immoral. However, if the OIC, or the NCOIC said “On my authority you are to follow my order” that meant you were not morally culpable (under the German system) for carrying out the order, the culpability was transferred to the higher authority. You had then to obey the order.
To presume that his 22 year old had any real authority in the matter of the camps is foolish, he had as much to do with running the camps as the enlisted folks that were scapegoats at Abu-grad in Iraq were a decade ago. I notice no officers were held culpable there only some enlisted shmucks who were following orders (illegal ones)
As to if he should be punished 71 years after the event is something I will leave to other folks. But it does seem to be a wee bit contradictory to have allowed so many actual NAZI members who had knowledge and a part in the Holocaust off rather lightly in 1947 to 1951, an then 65 years later try to make an example of this chap.
Ultimately only God know what is and was in his heart and will render the final judgment.
If those pleading that they were following orders are let off the hook, then the other argument that it happened so long ago becomes pointless because the law will apply also to the young. There need be no conscience or accountability for soldiers following orders. Is that your argument?
When abortion becomes illegal and many years later an abortion Doctor is caught, should we not prosecute him?
