First of all, Beowulf came to help Hrothgar on his own free will. Hearing of the troubles that Hrothgar was having with a monster terrorizing Herot, his mead hall, Beowulf bravely offered his help not knowing what he was up against. When he arrived, Beowulf did not ask the king for either money nor fame. The only favor that he asked of Hrothgar was that he and his men were to fight the monster, Grendel. Coming away from one's homeland to help get rid of a man-eating monster and asking for nothing in return takes much courage and is an extremely brave deed
