Answer:
His faith in God was deeply shaken by the events and the experience of the Holocaust.
Step-by-step explanation:
Elie Wiesel's autobiographical memoir "Night" is a recounting of Wiesel's memories about his earlier life as a Jewish in the concentration camps. The memoir serves as a witness's testament of the Holocaust and it's effects on the victims.
The excerpt provided in the question shows him questioning God in allowing him and the others to suffer even though they firmly belief in Him. Job was inflicted with boils all over his body even though God himself admitted that there's none like him in the whole world who have such strong faith. The book of Job details the many questions that Job has for God but in all, he did not ever flicker in his belief.
Likewise, Wiesel also began to wonder and question why this suffering can be silently accepted by God. He could not understand it in the least, stating that "[he] was not denying His existence, but I doubted His absolute justice." His faith in God was deeply shaken by his experiences during the Jewish genocide or the Holocaust.
