Does Amir have internal scars?

Amir has significant internal scars that haunt him as an adult. They stem from his traumatic childhood experiences and damaged relationships. As a child, Amir longs to have a loving relationship with his father, Baba. Amir wishes more than anything to gain his father's respect and earn his attention as a young boy. Tragically, Amir is not the masculine, athletic child his father always wanted, and Baba continually ignores Amir as a child. Baba constantly overlooks his son and seems to always favor Hassan over Amir, which negatively affects Amir's self-esteem and confidence. As a result of his father's callous nature and lack of admiration, Amir begins developing feelings of jealousy and envy toward his close friend, Hassan. Amir even begins teasing and tricking Hassan as a way to boost his self-esteem but always feels guilty afterward.

Unfortunately, Ali and Hassan decide to leave Baba's estate, and Amir eventually travels to America.
