Honestly it’s going into the realm of historical speculation. This simply would not have happened during the Holocaust, which is one reason I and other students and scholars of the Holocaust see this film and book as extremely problematic, and all together a poor representation of the Holocaust. First off, there is the problem of the story only creating empathy with Jews through a German character, it plays on a kind of writing where the minority character only has worth when viewed through the lens of a white person. The film was also criticized for an extraordinarily sanitized look at a camp. There is also the problem of knowledge. The character is a child, yes, but children growing up in these circumstances such as Hoess’ children or the children in towns near death camps like Oswiecim would have a pretty good idea of what was going on. It has been criticized for essentially supporting the post war German and in fact world wide reaction of “I didn’t know” when we know that knowledge of the Holocaust was widespread, and early too. That being said, the actual content of this would be impossible in a death camp. First prisoners did not have the ability to walk freely. And in death camps other than Auschwitz, there were no living child prisoners. In Auschwitz the commandant Rudolf Hoess did raise his family in a house on the grounds of the camp, however there were significant systems in place to prevent his children from interacting with prisoners and seeing and interacting with the camp. The second floor windows of Hoess’ house were clouded so the camp couldn’t be seen, and though the children knew what was going on they were not allowed to interact with the “dirty Jews” in the camp. A better representation of what the child of a commandant is seen in “The Kommendant’s Mistress” however this book has graphic descriptions of rape and murder so it isn’t for everyone. I would caution you not to take much stock in “The Boy in Stripped Pajamas” in favor of a fictional book like “Once” or “Milkweed” or nonfiction such as “Black Earth” by Timothy Snyder or “Into that Darkness”
