Good people become bad in a group. They lose their vision when it is subverted by the group vision. You see this in government. You see it in religion. You see it in this film. Gold knows what is right. He is offended by a black city official's anti-semitism. He is appalled by the Nazi atrocities against Jews. He wants to help, only to be betrayed by Jews who hold their cause above their humanity. Unto yourself be true.
