Wuthering Heights Big Question

Wuthering Heights revolves around revenge. One could argue that all misfortunes that Bronte's characters succumb to can be traced back to a grudge or a plan for revenge. So, if all the conflicts are caused by a character's need for revenge, could it be argued that the avenger is evil? Though it is a depressing book, I don't think so. Heathcliff  was originally a peasant in Liverpool, who was adopted by Mr. Earnshaw. As soon as he was taken in by the Earnshaw family, he was immediately shunned by everyone in the family except for Cathrine and Mr. Earnshaw himself. This isolation later drives Heathcliff to extreme levels of revenge, to the point where he starts treating his enemies' children badly. Heathcliff is turned into an evil man no doubt. But he wasn't a bad person to begin with. It was his environment that drove him to depression and hate.

If Heathcliff isn't inherently evil though, what about the people who drove him to evil? Hindley resented Heathcliff from the first night he spent at Wuthering Heights. Later, after Mr. Earnshaw and Hindley took control of Wuthering Heights, he cast out Heathcliff as a servant, denying him an education, despite the fact the they were brothers. Hindley's hate for Heathcliff was uncalled for, and was fueled by jealousy. He wasn't poor, he wasn't pushed away, he was just stuck up. Hindley was just jealous of his father's attention for Heathcliff.

These two men, who caused so much pain and suffering for the people around them, are both meant to be resented by the end of the book. They both fight with each other over childhood grudges, and harm they're loved ones in the process. They are both despicable. But Heathcliff was driven to hate, while Hindley was inherently stuck up and cruel. Society, like Hindley, falls into bad habits and morals. Individuals I think are not inherently evil, they're driven to evil by society, like Heathcliff was driven to evil by Hindley.
