a few of the characteristics from emerson's heroism that were necessary for defeating the monster Grendel were bravery, courage, and fearlessness. without Beowulf being courageous he would have never wanted to fight Grendel in the first place. Beowulf says "i shall manage the matter" meaning he will slay the monster no matter what it takes of him, which also shows his bravery. Beowulf talks as if he's talking to the monster and tells the monster basically to decide its own fate. This shows he's not afraid of Grendel.
