What central theme does Pip perceive in regard to Estella in Great Expectations?

In "Great Expectations," Pip perceives Estella as a tool for revenge, particularly in the context of her relationship with Miss Havisham. Miss Havisham, who was jilted at the altar, raises Estella to break men's hearts as a form of retribution against the male gender. Pip's infatuation with Estella leads him to recognize that she has been conditioned to be unloving and cruel, reflecting Miss Havisham's desire for vengeance rather than the natural expression of love and affection. This realization serves as a critical point in Pip's character development, as he grapples with the complexities of love, social class, and personal aspirations throughout the novel. Thus, Pip's understanding of Estella goes beyond a mere romantic interest; it reveals the deeper emotional and psychological implications of her upbringing and how that affects their dynamic.
