First, Heathcliff ruins Hindley by encouraging his excessive drinking and gambling habits. Once Hindley is dead, Heathcliff then turns his attention to Hareton. “Now, my good boy, you are mine!” And we will see if one tree will not grow as twisted as another, with the same wind to twist it” (p. 180). Healthcliff taking control of Hareton was part of his plot to avenge Hindley. A pattern of mistreatment is presented through Heathcliff's treatment of Hareton. Edgar having also wronged Heathcliff, by stealing Catherine from him, felt Heathcliff's wrath when he married Isabella. Isabella is Edgar's sister, and by marrying her he gets his foot in the door to eventually become the owner of Thrushcross Grange. Heathcliff continues his plan to own the Grange by forcing Linton (his son) and Cathy (Edgar's daughter) to marry, which guarantees his ownership of the Grange. Heathcliff's revenge on Edgar is complete, he has lost his sister, his daughter, his estate and finally suffers the death of Catherine. As Heathcliff approached death and moved closer to his reunion with Catherine, his desire for revenge dissolved until he had no credit left to avenge the unbelievers. he is wrong.
