How are Walt McCandless and Lewis Krakauer similar?

Krakauer’s relationship with his father, a fiercely competitive man who expects Jon to become a doctor, is very strained. Krakauer believes that only perfection will please his father, and he does his best to live up to these expectations, but when family secrets are revealed and he realizes his father himself is not perfect, his anger and resentment become extreme, and it is only decades later that he can accept his father as human. This is a similar case with Chris and his father. The difference is that Krakauer finally accepted his father as human and thus imperfect, Chris never did this with his father.
