It is not a question of whether we can forgive a seemingly unforgivable atrocity; we, as the third party to events, cannot. Yet, the increased interest that forgiveness has been given over the preceding decades, as the post-witness era draws closer, is a telling sign that by exploring forgiveness there may be much to learn.
It's how and why the memories of one of the darkest moments in human history should be kept alive that formed the theme of the film. And during the months making it I was struck by the myriad of ways those who suffered the atrocities of the Holocaust have chosen to pass their memories on. How they refuse to allow the echo of what they witnessed fade.
We are often told that as Jews, we should end our "unhealthy obsession" with the Holocaust; that it is now time to move on. Whilst this may seem sacrilegious to some, as an educator, I would like to suggest that perhaps we do need to re-evaluate the messages that we take from this darkest period of recent Jewish history and their long term import.
The Holocaust was a genocide, a systematic, bureaucratic, state-sponsored persecution and murder of Jews by the Nazi regime and its collaborators. As President Shimon Peres has said, it was "the greatest darkness that mankind has known". Jews were abandoned by humanity. But there were human beings who were sensitive to this tragedy...
Remembering and marking the Holocaust is one of the most important things that we as a society can do. If we fail to remember and learn from the past, then we are surely doomed to repeat past mistakes. Commemorating the Holocaust is essential to educating our children and others who may not know or be sufficiently familiar with the horrific, unique and unprecedented events of the 1930s and 1940s in Nazi Europe. Educating society on the horrors of the Holocaust is perhaps now, 70 years on from the liberation of Auschwitz-Birkenau and other concentration and death camps, more important than ever.
By now you'll have probably heard of Breanna Mitchell, the teenage girl who posted a selfie smiling at Auschwitz concentration camp. Although she posted the photo some time ago (June 20th), it has only recently gone viral - clocking up more than 3300 retweets and a barrage of abuse over the past few days.
