Final answer:
Elie Wiesel called his memoir 'Night' to represent the darkness of the Holocaust, the loss of faith, and the moral ambiguity experienced during that time.
Step-by-step explanation:
The memoir Night by Elie Wiesel bears a title that carries significant metaphorical weight. Wiesel's choice to name his memoir Night represents the darkness, despair, and evil that he experienced during the Holocaust. Nighttime often symbolizes a lack of vision and moral direction, which aligns with the moral ambiguity and atrocity witnessed during this period. Additionally, night may signify the absence of God, which reflects Wiesel's struggle with faith in the face of the Holocaust horrors.
