Heathcliff's obsession

Heathcliff's Obsession Throughout Wuthering Heights, Heathcliff's personality could be defined as dark, menacing, and brooding. He is a dangerous character, with rapidly changing moods, capable of deep-seeded hatred, and incapable, it seems, of any kind of forgiveness or compromise. In the first 33 chapters, the text clearly establishes Heathcliff as an untamed, volatile, wild man and establishes his great love of Catherine and her usage of him as the source of his ill humor and resentment …

…reasonable and rational in his love for Catherine--his behavior, as illustrated in the last chapter was erratic, and his death disturbing--all indications that Heathcliff was wildly obsessed with Catherine, a premise which does much to resolve many of the complexities in Chapter 34. Bronte does an excellent job of introducing complexities and tensions within the text and then resolving them subtlety and exquisitely through Nelly's narration and observations and through Heathcliff's wild moods and unpredictable actions.
