"The real answers, Elizer, you will find only within yourself". What are the most significant questions that Elie asks, and what answers does he find?

Elie asks some hard questions about his faith and humanity. Elie cannot imagine the deprivation of what the soldiers do to the prisoners and what the prisoners inflict on each other. Elie was once a devout follower of the Jewish faith. As the novel continues, Ellie cannot accept that a benevolent God would let this happen to his own people. 

"Never shall I forget those moments which murdered my God and my soul and turned my dreams to dust. Never shall I forget these things, even if I am condemned to live as long as God Himself."
