I think he is a hero. He is very arrogant, like when he bragged about
his father, he bragged about killing other monsters, and he bragged
that he could kill Grendel. I still think he's a hero though, because
when he decides to go kill Grendel, I believe he didn't do it all for
himself. He did know that death could come to him, but it didn't
matter. Also, he comes back to kill Grendel's mom, even though he's
accomplished what he wanted, he does it to save the people. He has
many characteristics of Hubris because the pride he has comes off as
arrogant, but he actually does have the power to do what he brags
about.
