If Beowulf was written by Grendel I think the story would have had a very different outcome than it did with Beowulf as the protagonist.Grendel was a very mean and selfish person who was scared of everyone but Beowulf. In the part of the story about the battle with Grendel I think that if Grendel was writing the passage he might have changed the part in the story where Beowulf beat him up. He might have said that he himself defeated the great Beowulf.He would have left that part out because he would be embarrassed if people knew the truth about what happened between them two. He also might have said that he killed Beowulf instead of Beowulf killing him. I also think that he would have left out the part that Beowulf killed his mother. He would have definitely left the part out where it talks about the mom battling Beowulf because he probably wouldn't want his mother fighting Beowulf. Grendel would have also left out the part where Beowulf steps in for the Danes in order to be kept safe. Grendel would have left in the part where he killed the Danes when they were in the mead hall asleep. This is what i think Grendel would have done if he was the protagonist.
