Final answer:
Sohrab shooting out Assef's eye represents a moment of justice against oppression, a pivotal narrative turn, and underlines themes of good versus evil and fate.
Step-by-step explanation:
The significance of Sohrab shooting out Assef's eye with his slingshot is multifaceted. It serves as a moment of retribution and justice for the years of Assef's brutal and oppressive behavior, especially towards Sohrab and his family. This act symbolizes a turning point in the narrative, where the oppressed stands up against the oppressor, embodying the theme of the deliverance of justice and the role of fate or destiny in the lives of the characters.
Additionally, it connects deeply with the themes of good versus evil and the concept of comeuppance in literature. Sohrab's precise aim, despite being a child, also underlines the unexpected ways in which justice can be delivered and the notion that no matter how powerful the antagonist may seem, they are not invincible.
