Wuthering Heights by Emily Brontë - Heathcliff, a protagonist or antagonist?

Wuthering Heights Wuthering Heights may be perceived to be just another novel, waiting to be read by the average reader, sitting on some remote bookshelf. This narrow-mindedness will be out of the mind of the reader when he turns past the first page; this novel is anything but conventional. Some characters have more depth to us than many real-life people, and one such character is Heathcliff. Ravaged by the past and bent on avenging everyone …

…first few chapters. It is usual for Emily Brontë to let characters just die off after they're no longer needed: this has happened with the Mr and Mrs Earnshaw, Linton, Hindley, and others. Other characters can't be the protagonists since they have so little involvement in the main story. The only two main characters can be Heathcliff and Catherine. That's why I firmly stand on the belief that Heathcliff is a protagonist in this novel.
