Certainly, the idea of fear and hatred playing into how people perceive their own lives is a part of Miller's work. Abigail's own background might prove such a point. Her parents dying when Abigail was such a young age left a tremendous and gaping hole in her own life. There must have been some level of envy and hatred for those whose own life was nowhere near as difficult as her own. Part of the reason why Abigail possesses so much anger and is responsible for so devious a plot is because of her sense of envy of others and their own happiness. She wishes to usurp Elizabeth's role with this sense of hatred and envy in mind. Abigail's own life circumstances help to compel her to begin the deception that grips the entire town. It is fitting that she does not receive any sort of justice from the town, but rather runs away to Boston, presumably to become a prostitute, demonstrating how a sense of hatred of her own life's circumstances helped to drive her farther away from any conception of happiness.
