What Are The Father-Son Relationships In The Night?

In the book Night, Elie Wiesel shows the evolution of his relationship with his father during the Holocaust.
At the beginning of the book, Elie’s close bond with his father was hidden. Wiesel describes his relationship with his father, “He [Elie’s father] rarely displayed his feelings, not even within his family, and was more involved with the welfare of others than that of his own kin.” It seemed that Elie’s father did not care about his family as much as the family of others. Earlier in the book, it is stated that he was an unsentimental man, meaning that he did not like showing his feelings.
Towards the middle of the book, more and more was revealed about how close Elie and his father were. After hearing the news of an evacuation, Elie shared a moment he had while thinking of his father, “As for me, I was thinking not about death but about not wanting to be separated from my father. We had already suffered so much, endured so much together. This was not the moment to separate.” When the prisoners heard the news of the evacuation to Buchenwald, Elie was only thinking about staying with his father, while the others were thinking about death.
At the end of the book, Elie’s relationship with his father was tested. While remembering his father’s death, Elie portrayed a sentimental moment, “His [Elie’s father] last word had been my name. He had called out to me and I had not answered. I did not weep, and it pained me that I could not weep.” He was aware that his father’s last word had been his name, and he felt terrible that he did not cry for him. “Since my father’s death, nothing mattered to me anymore.” Elie was so heartbroken that nothing he said or did mattered. His father was the only reason he lived, and now he was gone.
