Who were some upstanders in this book?

One major conflict presented in the book is the conflict between non-Jewish Germans and European Jews. Many Germans during World War II may not have known about the genocide taking place in concentration camps. However, they certainly knew that Hitler was anti-Semitic and blamed Germany's problems on Jewish people. Yet many Germans still supported Hitler, even when it was clear Jewish people would not be allowed to live and work as they had in the past.
