Describe the ways in which Amir seeks redemption?

I think that the act of going back to Afghanistan reflects
a step towards redemption.  In being able to confront his life from what it was to what
it is represents a homecoming of sorts, and a redemption in the process.  At the same
time, I think that the understanding of his true relationship with Hassan the compulsion
to adopt Sohrab represents another part of this redemption.  Amir understands that he is
responsible for establishing a moral order in a setting where none exists.  In the
condition that the Taliban created in Afghanistan, and understanding the fate that
Sohrab would probably face, Amir comprehends his responsibility.  In this, there is
redemption.  The mistakes he made with Hassan in not taking action and being silent are
not what he will make with Sohrab.  In this, there is redemption that demonstrates both
an evolution of character as well as the potential hope for the
future.
