The boy matures over the course of this journey, and his changing relationship with his father reflects this growing maturity. At the beginning of the novel, the boy looks to the father for knowledge and guidance, believing his father to speak the truth unequivocally. However, as he gains new experiences, the boy learns to use his own judgment and can assess somewhat better whether or not his father is telling the truth. He begins to question his father's honesty on such matters as whether or not they are truly the "good guys" and asserts his own opinion when believing that they should help other people. He never doubts his father’s love for him, however, and continues to love and trust his father, even while he begins to have more and more serious reservations about his father’s choices. In a sense, it is time for the father to die when the son is mature enough to make his own moral decisions for the new generation.
