If he actually is guilty of the accusation, he had to have been waiting and expecting this day and by some odd twist of fate avoided justice until he was a very old man. He’s lived to an advanced age, something he denied a lot of other people, if guilty. I have little sympathy, unless he’s being wrongly accused. If the matter was broached 20 years ago and his denial of involvement was accepted at that time, I’d assume that there must be new information that has come to light.
From the description of what he personally did when employed, he didn’t steer a single Jew into a single oven. I’m sure he may have felt shame that he risked being put into a position to do that, but at the same time why not relief that by the grace of God it did not happen? I say this case verges on witch hunt, and so did any prior parallel cases.
