Describe the scene on the train. How do Jew react to Madame Schacter's behavior? What is revealed about human nature?

The train is cramped. There is no ventilation or bathrooms. The only light or air is had through the holes in the sides of the boxcar. Madame Schaechter is in the same train car as Eliezer during the initial deportation to Auschwitz. She had been separated from her husband and two older sons, and she is accompanied by another younger son. She loses her mind during the journey and screams hysterically and repeatedly about a flaming furnace that she apparently sees in the distance. She terrifies the other occupants of the train, and she is repeatedly beaten by young men trying to silence her.
