It all seemed desperately hopeless and sad but hope came in the battle waged by those who stayed and continued to bravely confront the crimes of their forefathers head on. Rainer Hoess travelled back to Auschwitz to meet survivors of his grandfather’s camp. Niklas Frank has written books and travels around schools to talk to teenagers about his Nazi father. Barely looking over his glasses he told the blank faces in front of him how he knew they were bored of hearing this stuff but that if he didn’t go on “executing” his parents every day like this the evil could easily return. He could have been talking to TV viewers, numb to another Nazi documentary, but this one was devastating in how powerfully it reached into the living heart of our dark past.
