Explanation:

Wiesel wrote "The Perils of Indifference" in order to show how dangerous indifference can be in the world. He tells us about his experiences during the Holocaust, and how he believes the main reason why these atrocities were possible was because people were not paying attention. And even those who were did not care enough to put a stop to it. Therefore, he asks us to avoid indifference and instead do something when we see human suffering.
