Heathcliff and Hareton Earnshaw's relationship

The relationship between Heathcliff and Hareton Earnshaw is among the most sustained and contradictory forces in Wuthering Heights: it begins as a calculated act of vengeance, hardens into a system of deliberate degradation, and then unexpectedly softens into a bond of genuine, if strange, affection—before finally becoming the very thing that breaks Heathcliff's will to destroy. It is a relationship built on the ruins of another enmity, Heathcliff's lifelong hatred of Hareton's father, Hindley Earnshaw, and it carries within it the novel's deepest questions about inheritance, nurture, and whether the sins of the fathers must be visited upon the sons. Its arc—from oppression to attachment to a kind of redemption—mirrors the larger movement of the book from the violent passions of the first generation to the quieter, more hopeful possibilities of the second.
