That is an interesting story. I've known people who were in the camps - most of them met when I lived in New York. Would see the faded blue tattooed number on their forearms - it was tough to see. Tough to hear about as well.
For what it's worth I think you made the right call. It's like trying to put a positive spin on Amon Goeth from Shindler's List - impossible. Than ks for the story.
