What does the narrator discover about hate after he attacks the waitress

In "Notes of a Native Son", a series of essays written by American novelist James Baldwin, the author analyzes race relations, and displays his own experiences with racism as a moral lesson.

The narrator shares his understanding on how slave descendants should not react to racism; excerpting it from his own reactions to racism, particularly one of his experiences in a racist restaurant he was working at, when he felt an urge to violence and attacked a waitress out of his own bitterness and hatred, realizing that Black Americans could become their own enemy if they confront hatred with hatred.
