The Kite Runner 13-15

I think Soraya and  Amir are good together, even though they didn't really know each other during their engagement. I think Amir's relationship with Soraya shows that Amir isn't a bad guy, and he does have some goodness in him. If you were to actually count when Amir "becomes" good, then I would choose the part when Amir goes to see Rahim back in Peshawar. He then finds out the information he would never expect and he realizes he must make things right again.
