Heathcliff gets revenge on Catherine and Edgar Linton by eloping with Isabella Linton and then treating her horribly. He gets further revenge by forcing their son, Linton, to marry Edgar's daughter Cathy, thereby inheriting Thrushcross Grange when the sickly Linton dies soon after.
Answer and Explanation: Heathcliff's desire for revenge stems from his loss of Catherine, first to marriage and then to death.
Heathcliff is Angry with Catherine
Catherine claims that both Edgar and Heathcliff have killed her by breaking her heart.
As Nelly searches for a gate key, Heathcliff appears, scolding Cathy for ending her communication with Linton and accusing her of toying with his emotions.
The best example of revenge is Heathcliff's treatment of Catherine for her betrayal and marriage with Edgar. He separated her daughter from Edgar and was cruel to her afterward. Other examples of vengeance include Hindley's hate of Heathcliff and Heathcliff's maltreatment of Hindley's son, Hareton.
Heathcliff then takes revenge upon Hindley by, first, dispossessing Hindley of Wuthering Heights and by denying an education to Hareton, Hindley's son. Heathcliff also seeks revenge on Edgar for marrying Catherine by marrying Cathy to Linton.
Answer and Explanation: The narration of Emily Bronte's Wuthering Heights never indicates that the revenge pursued in the novel is justified, but Nelly Dean's narration helps the reader understand why Heathcliff feels the need to revenge himself on others.
Heathcliff puts Cathy over his knee as if she is a little child and boxes her head; yet his remark concerning his ability to punish children is ironic in light of his childish behavior, of his infantile possessiveness and impulsiveness – he clings to the key in a skirmish of literal tooth and nail.
Nelly looks for the key to the gate, and suddenly Heathcliff appears, telling Cathy that it was cruel of her to break off her correspondence with Linton. He accuses her of toying with his son's affections, and he urges her to visit Linton while he is away the following week.
He curses Catherine for the pain she has caused him, and pleads with her spirit to haunt him for the rest of his life. She may take any form, he says, and even drive him mad—as long as she stays with him. Edgar keeps a vigil over Catherine's body. At night, Heathcliff lurks in the garden outside.
In chapter 29 of Wuthering Heights, Heathcliff tells Nelly Dean about how he dug up Catherine's body just after she was buried, back in chapter sixteen. Heathcliff went alone to the churchyard and, wild in grief for Catherine, dug down to her coffin and attempted to wrench it open.
Isabella reveals that Heathcliff blames Edgar for Catherine's suffering, and he will take this out on Isabella, too.
As noted above, there does not seem to be any evidence that Catherine ever slept with Heathcliff so we can be reasonably certain that Cathy was Edgar's.
Isabella's Love for Heathcliff
The reader, Catherine, and Edgar know that Heathcliff is there for Catherine, but when Edgar's young sister, Isabella, becomes attracted to Heathcliff, reason flies out the window, creating dramatic irony. Like many young people in love, Isabella refuses to listen to Catherine's warnings.
After Catherine's marriage to Edgar, it becomes Edgar's job to try to keep Heathcliff and Catherine apart. To get revenge against Edgar for taking Catherine from him, Heathcliff marries Edgar's sister, Isabella, and treats her badly.
Heathcliff as a Victim
It is worth mentioning that Hindley is the first one who started abusing and victimizing Heathcliff though he was just a child at that time. He abused Heathcliff physically by knocking him down with a heavy iron weight and kicked him under a pony's hoofs.
When Catherine sees the wounds on Heathcliff's back from some mysterious master or parent, she doesn't treat them or kiss them, she licks them, as though it's her only sustenance in this overwhelming landscape that swallows people whole.
Their relationship is portrayed in scenes of play that quickly become about domination and power. Cathy expresses her love by pulling out Heathcliff's hair and literally licking his wounds. Her actions are no less menacing when she takes advantage of Edgar's weak nature.
Heathcliff tells Nelly that he persuaded the sexton to dig up Catherine's grave. He stares at her dusty corpse and bribes the sexton to put his body next to hers when he dies. He has no fear of disturbing the dead, he tells Nelly. Cathy has been haunting him for eighteen years.
Cathy tries to fight for the key, but Heathcliff slaps her upside the head. He vows to be her father-in-law by morning. Linton refuses to help Cathy and Nelly escape, as he is more interested in saving his own skin than in letting Cathy be with her father on his deathbed.
There aren't any sex scenes between Cathy and Heathcliff or even implied. True, there are scenes with sexual undertones but Heathcliff has a very physical desire for Cathy. Had they actually had sex, their relationship might have gone on longer or might not have as the tensions would have been relieved.
Answer: In Wuthering Heights, Сatherine dies early - not from an illness, but from an exploding soul that could not bear the mistakes in her marriage choice. She died after childbirth, leaving a daughter, Сathy.
Heathcliff from Wuthering Heights by Emily Brontë
Upon Heathcliff's arrival, he is faced with oppression, violence and hatred. This leads to Heathcliff vowing revenge on all who contributed to his pain and suffering – the ambitious Heathcliff ultimately causes his own downfall by being fuelled by hate.
Heathcliff, the protagonist of Wuthering Heights, is abusive and aggressive. One example of his abusive behavior is when he hangs Isabella's dog. Another instance of his brutality is the way that he treats his wife.
I'm too happy; and yet I'm not happy enough. My soul's bliss kills my body, but does not satisfy itself. ' In these final words before his death, Heathcliff talks to Nelly about his current physical and mental state.
