What did the treatment of Madame Schachter reveal about what was happening to the community?

Since Madame Schaechter's hysterical shrieks was unnerving everyone in the car, he recognizes that it was necessary for their collective survival that she be silenced. At the same time, however, he seems to mourn the fact that such cruel behavior was necessary and that everyone, including the woman's own son, condoned such violent and vicious behavior. In this nightmare world that the Nazis have created for the Jews, survival is the only concern, and human emotions and affective ties become irrelevant. Madame Schachter's outbursts are not hysteria and prove to be rather prophetic as they reach the camps where the sky is filled with fire.
