What is the author's purpose in writing the selected piece?

The author's purpose in writing Grendel was to show how there are two sides to every story. He does this by telling the story through the eyes of Grendel, the historical villian in the epic poem Beowulf. This is also a commentary on the Vietnam war. He tries to show that there are two sides to this story also and that we can't simply view Vietnam as evil. He aims to say that there are more complex issues behind the conflict and they also need to be evaluated. He tries to counter the propaganda techniques used during the war that tried to dehumanize and demonize the vietnamese.
