Is Grendel a Monster?

Whether or not Grendel is a monster is an often asked question but the answer is somewhat uncertain. To the townspeople Grendel is a sinister, evil, vicious beast that thrives on devouring innocent humans. They think about the fact that Grendel has killed their friends and family. The reason they see Grendel as such a monster is because they're thinking about things from their perspective only. Another thing they aren't taking into consideration is the fact that Grendel is somewhat like themselves. This really goes under the saying of "let he who without sin, cast the first stone." The reason I say this is because they are slaughtering living things just like Grendel is slaughtering them. My opinion is that Grendel might not be the monster that people think he is. I mean, the townspeople a re constantly killing animals and selling them but they don't consider themselves to be monsters. The townspeople feasted on many animals as a way to survive. So maybe in Grendel's case he is just doing the same. Many of the townspeople called Grendel a monster because he laughed while feasting on their friends and family. Though at the same time they celebrated and partied while feasting on animals. This story is kind of representing karma. That's why I think Grendel isn't the complete monster he is made out to be.
