In The Kite Runner, what is Baba's view of religion?

Baba finds that religion is really an excuse for all kinds
of behavior that he finds despicable.  At the same time he thinks it is very important
to act honestly and he spends a great deal of time and effort being sure that Amir
learns these lessons.  Part of his problem with religion may be due to the fact that
organized religion prevents him from publicly accepting his son Hassan whose mother was
a Hazara.  Part of it is also likely due to the way that he sees fundamentalist
religious leaders tear his country apart after the overthrow of the
Soviets.
