It only takes one person to start a cycle of hatred and repeated suffering, but also one person to break this chain and bring happiness to the world. Relationships in Wuthering Heights are based on envy and revenge and bring only pain. This is ironic because the abuser thinks this will bring relief from his pain. But Brontë emphasizes the futility of revenge, because even when accomplished, it does not fulfill its purpose of relieving pain or restoring love. This can only be achieved when people stay true to the path of love and are tenacious enough to overcome their difficulties.
