In this scene, Guido pretends to be able to speak German so he can help his son believe that its all a game. He interpreted what the German is saying into Italian so Joshua believes its real.

Who are the heroes and villains in this scene? Why are they heroes and villains?
In this scene Guido is both a hero and a villain, he is a hero because he is trying to protect Joshua and make him believe in what he said before but he's a villain because he is putting the others in danger because they then don't know what the German was actually saying. The German man is also a villain because he is telling the Jews what they HAVE to do and laying down the rules.
