whatss the worst thing humbert does?

In Vladimir Nabokov's novel "Lolita," the character Humbert Humbert engages in numerous morally reprehensible actions, but one of the worst and most significant is his sexual abuse and exploitation of the young girl, Dolores Haze (whom he nicknames "Lolita"). Humbert's obsession leads him to manipulate and coerce her into a relationship that is both psychologically and physically damaging. He takes advantage of her youth and vulnerability, causing her profound harm and robbing her of her childhood. This central act of abuse serves as the foundation for the novel's exploration of obsession, power dynamics, and moral ambiguity.
