Wuthering Heights' tragic hero, Heathcliff is responsible, in some ways for all of the misery that binds the story together. Social class weighs heavily in the themes as Heathcliff is poor and of a lower class than Cathy and her father. Becauwe of this Heathcliff suffered at the hands of most of those around him. After a while Heathcliff begins to believe the slurs and the context of all of those 'above' him. Because of the social class system, neither Catherine or Heathcliff were happy because they both married someone within their social class. It was only in death that they escaped the tragedy of their lives.
