In Night By Elie Wiesel, humanity was lost in the camps. Note acts of kindness and signs of hope in the midst of the bestiality.
This one won't be easy. Simply put, Wiesel's narrative displays how human kindness was a rarity in the camps. The dentist's generosity at Buna in letting Elie go would be one such example. Since he is executed for both this and the perception that he stole, it can be presumed that the dentist was not the norm. At Auschwitz, when Elie is told to lie about his age, that might be seen as an act of kindness in that it is intended to help him stay alive. Eliezer comes to think of this in another light when recognizing that a true dislosure of his age might have allowed him to stay with his mother, albeit die with her. The French girl at Buna is an example of someone who represents the idea of a haven in a heartless world. As she helps Eliezer out, there is a distinct feeling of some level of humanity presented in a setting where only the worst are on display. The fact that later on, Wiesel was able to recognize her, and understand that the girl took great risk in speaking to him and helping him confirms that there was a moment, an instant, of humanity in a setting that was fairly devoid of it.
