Wuthering Heights

That shows Catherine remains a free spirit at heart and is attracted to one of similar personality.
             Heathcliff is not blood related to any of the characters in Wuthering Heights. He was adopted by Mr Earnshaw of Wuthering Heights. His name Heathcliff acts as both a Christian and a surname thus placing him outside all the social positions of the area and conveying him as an outsider.
             Heathcliff is described throughout the novel like an animal - "growled Mr Heathcliff his whiskers encroached bearishly he's a fierce, pitiless, wolfish man" - or the devil. The reference to the devil is related to the sense of heaven and hell, which is also a theme in the novel. Heathcliff is in part a romantic, passionate man but is also violent in ways that would be considered out of keeping for a gentleman of the time. These traits come out in the novel in the form of his extreme cruelty which e uses on many of the characters like Linton and Cathy who he uses as tools to get his revenge. The revenge in this respect is the hatred and jealousy Heathcliff feels towards Edgar for marrying Catherine and towards Hindley for treating him badly as a child. There is no doubt Heathcliff has a chip on his shoulder and wants to prove himself better than the rest.
             When he arrived at Wuthering Heights, Nelly described her impressions of him as "a dark skinned gypsy" and "dirty, ragged, black-haired child". He did not fit into the family and although was loved by Mr Earnshaw and Catherine, he was hated by Catherine's brother Hindley who bullied him continuously. His personality is described as one of a "sullen, patient child; hardened perhaps, to ill treatment". It would also appear that he was mischievous like Catherine, the two were very similar in personality and interests. Heathcliff falls in love with Catherine and he wants to be with her forever. When she accepted the proposal from Edgar it destroyed Heathcliff and he disappeared for 3 years.
