Hans had to face and hide from the Nazi regime, as did the Jewish children.
Explanation:
Hans was not a Jew, but because he was against the Nazi regime, he had to hide and face him as he could, at the risk of being discovered, captured and tortured, as well as Jewish children. That's because Hans hid a son of a Jew in his home, helped the Jews he encountered, erased anti-Semitic messages hidden and did everything he could to not be captured.
We can say that the similarities between him and the Jewish children were fear, which both felt during the war.
