Final answer:
Elie Wiesel chooses not to fast on Yom Kippur for two reasons: loss of faith and a desire for autonomy amidst the suffering of the concentration camps.
Step-by-step explanation:
The question references a scene from Elie Wiesel's memoir Night, which discusses why Elie chooses not to fast on Yom Kippur, despite it being a significant holy day for Jews.
Two reasons Elie gives for not fasting are his loss of faith in religious rituals after witnessing so much suffering, and a desire to assert some control over his life by choosing when and when not to fast, an opportunity for autonomy amidst the deprivation of the camps.
This act can also be perceived as an act of rebellion against those trying to impose their will upon him, including the Nazis and even God.
