Hello. You forgot to say that this question is about the book "Night", by Elie Wiesel.
Answer:
Because he feels overwhelmed by having to take care of his father in this situation.
Explanation:
In the book Elie Wiesel and her father are trapped in a Nazi concentration camp, suffering all possible abuse because they are Jewish. Although they love and care for each other, the situation in the camps is more and more decadent and as their strength and perseverance diminishes, their loyalty between them becomes increasingly fragile.
Elie takes care of her father who is older and more fragile in that oppressive system, but the situation is so difficult and degrading, that Elie sometimes wants to find it oppressive to take care of his father and believes that his life would be easier if he were alone in the field.
This is even more evident when Elie's father contracts a deadly case of dysentery and is attacked by a Nazi soldier who breaks his skull with a blow. Elie's father is in a deplorable situation and in extreme agony whispers the name of Elie who does not answer, because he thinks this will be a very difficult burden to bear.
