Well, in the film, he's responsible for the Amittyville Horror (which I assume you're familiar with), and then proceeding to haunt an English family, uses an elderly ghost as a pawn by forcing him to haunt the family (and also kept him from passing on), possessing the young girl, and ultimately trying to cause her to jump out of the window and impale herself, etc. He exists to corrupt and pervert, so there's his purpose. As I had mentioned, there's nothing to indicate that he's made of evil, and is smart enough to mastermind this type of haunting.
