Is Grendel a Monster?

I think that Grendel is a monster, because even though he was part human he still ate people. There's no justification for eating people unless you're a wild animal or in this case a monster. Then it's just looked at as horrible, but unpredictable. Throughout the story he showed wild animal or monster-like characteristics, even though he was considered a child and supposedly didn't know any better. His mother still treated him like a child, but only because she was his mother. The story from Grendel's point of view shows him in a different light. He showed human characteristics and showed Beowulf as a monster. He had articulation and a thought process. However, he was still excited about the fact that he was eating people. That's the only problem I have with giving him his "Human (Not Monster) Card."
