To show that cruel behavior is not limited to only one situation.

Explanation:

Elie Weisel's memoir Night tells his experiences during the Holocaust and the discrimination the Jews faced at the hands of the German Nazis. The book also became one of the most famous and important pieces of information about one of the most horrendous genocides in the world's history.

As seen in the given excerpt, the author narrates how he had witnessed a "stampede" kind of situation among the prisoners over a small piece of bread that a worker had thrown into the wagon. And similar to this event, he also recollects how an elegant Parisian lady had done "charity" work by throwing coins to the natives on the Aden which only led to the "natives" diving into the water to retrieve them. These two scenes seemed so similar to each other, leading Weisel to conclude that cruel behavior is not limited to just a single situation but could also be seen in numerous ones, however unlike they may seem.
