Chapter 8 and 9 what is the impact of the father's death?would his survival have affected the story in a positive or negative way

In Chapter Nine, we learn that Eliezer does not weep for his father because he no longer has any more tears. And he admits that deep down inside himself, he feels freed by his father's death.

In Chapter Ten, we find that Eliezer remains at Buchenwald until April 11. He has nothing to say of these last months in the concentration camps because after his father's death, he became indifferent and emotionless, concerned only with eating. Though Eliezer feels relieved when his father dies, it is clear that this emotion is merely a momentary one that he later deeply regrets. For after his father's death, Eliezer's life in the concentration camp also ceases to really exist: "I have nothing to say of my life during this period. It no longer mattered. After my father's death, nothing could touch me any more." The narrative ends rather abruptly after his father dies because to Eliezer, there is really no more story to tell. His story of life at Auschwitz and Buna has been one in which he and his father struggled together to survive, and after he dies, details become irrelevant.

Had Eliezer's father survived, those last months would have been much the same, but in my opinoin, freedom would have been that much sweeter. The father and son had been through hell on earth..... and they went through it together. It must have been difficult for Eliezer to see the future and freedom without him...... for his father to have come so close, yet die.
