This question refers to the character Hazel from the novel "The Catcher in the Rye" by J.D. Salinger. Hazel is not a character in the book, but Holden Caulfield, the protagonist, is known for his cynical and disillusioned perspective.
Holden does not blind himself in the novel. He is, however, deeply troubled by the world around him and feels alienated from society. He expresses a strong sense of disgust towards the phoniness and hypocrisy he perceives in adults and his peers.
Holden's actions and thoughts throughout the novel, including his desire to protect children from the "phony" world, are often interpreted as signs of his emotional distress and his struggle to find meaning and authenticity.
While he does not physically harm himself, his emotional turmoil and alienation manifest in other ways, such as his frequent lying, his tendency to withdraw from others, and his general sense of despair.
