In The Kite Runner, how does Baba feel about his son?

While they are still living in Afghanistan, Baba shows
great disappointment in his son. Aside from Amir's literary pursuits, which Baba frowns
upon, Baba has noticed that Hassan has had to defend Amir from the taunts and threats of
other boys. Baba rightly perceives this as a weakness on Amir's part, and his son's lack
of interest in sports and other physical endeavors further infuriates him. Baba finally
has a reason to be proud when Amir wins the kite flying contest, but that soon changes
when Amir asks his father to consider dismissing Ali and Hassan from the house. When
Amir firmly rejects Amir's request, Amir shamefully plants his own birthday presents
under Hassan's mattress in order to disgrace Hassan.

Things
change for the better once Baba and Amir flee to America. Baba's own social and
political power has been shattered, and Amir slowly grows into a mature
adult, graduating from college and achieving his goal of being a published writer. Amir
marries a woman he loves, instilling further pride in Baba; and upon Baba's death, the
two have become closer than they ever have.
