He was a handsome man. My Great Grandmother died in that war, but I don't have any hard feelings. I never met her. Apparently she died in one of the camps. We are Jewish, ethically (messianic) Don't think I resent your grandfather or anything. It is history. In the past. I know I will never forget about the events, but I don't hold any grudges. That is not what my great Oma would have wanted.
As bad as the results of the ss were, your grandfather believed himself to be a man of honor to his country. No one doubts Hitler was one of the finest orators in the world and for the most part to not follow Germany at that time was cowardice. Hindsight has a different opinion of course. I have also heard that only about 7%of the Germans that surrendered to the Russians ever made it back alive. As a member of the SS it is amazing he made it back at all. Right or wrong, your grandfather was a man of honor, courage and creativity. You have a LOT to live up to. I sincerely wish you both the best. PS - my father received the purple heart after freezing in the N Atlantic and losing 1200+ men. Enough of him didn't freeze when he returned and I was the result (grin). They all have stories and memories that they will ultimately be able to share only with the grave, not us. That detracts nothing from the quality of the man that had to go through it. My deepest compliments and appreciation to both you and your Grandfather for sharing such a bold step. I wish I could get to know such people of integrity and courage more before my clock runs out too.
