In Chapter 4 in the book NIGHT by Elie Wiesel, why are the men filled with joy as the bombs fall around them? What does this show about them?

The men are filled with joy as the bombs fall around them because they want the Germans to be defeated. Wiesel mentions how they've heard the Germans were losing some battles, but this was the first time they had proof. This shows that they "no longer fear death". They have been living with so much death that it is a regular occurrence. Also, a death that is caused as a result of Germany's defeat is better than a death at the hands of the Germans.
