Final answer:
Elie Wiesel's faith in God is profoundly challenged by the execution of a young boy by the Gestapo, as well as by the overall suffering experienced during the Holocaust. These events cause him to question the existence and benevolence of God, ultimately leading to a significant spiritual crisis.
Step-by-step explanation:
Elie Wiesel's experience in the Holocaust as depicted in his book 'Night' provides profound and harrowing evidence of moments where his faith in God is severely challenged. Two pieces of evidence from the text that indicate the breaking of Wiesel's faith include the execution of a young boy who refused to give information to the Gestapo, a chilling event that famously elicits the response from Wiesel about the death of God. Secondly, the cumulative suffering witnessed throughout his experiences, including the loss of innocence and humanity, contribute vastly to his spiritual turmoil and doubt in God's existence or benevolence during such atrocities.
The execution of the boy is a central moment that shatters the faith of the observers. The innocent boy's hanging, particularly its cruelty and the boy's prolonged suffering, causes Wiesel to question the nature of God and invokes the sentiment where he observes the death of his own faith mirrored by the child's literal death. Another key moment comes from the overall experience of injustice and suffering that Wiesel endures and observes in the camps, which erodes his faith and challenges his belief system profoundly.
