How are Soraya and Amir alike and different in The Kite Runner?

The characters of Soraya and Amir share many
similarities. Both have grown up in Afghanistan as the children of powerful, influential
fathers: Baba is a rich philanthropist, while Iqbal Taheri is an army general. Both Amir
and Soraya share dark secrets in their past: Amir's betrayal of Hassan haunts him
continuously, while Soraya's affair with a past boyfriend has tainted her reputation and
caused distress in the family. They have each caused harm to their mothers: Amir's
mother died during childbirth, while Soraya's mother suffered a stroke when she ran away
from home. Both Amir and Soraya wonder if they are worthy of the other. They each yearn
for children, but Soraya is unable to have one of her own. Following their marriage, the
relationships with their parents improve, and they seem to thrive on the independence
they have apart from them.
