It is likely that there are several reasons why Beowulf and the Geats return to King Hrothgar and the Danes.
- Beowulf wants to bring proof that the monster is dead.
- Beowulf wants to silence Unferth, who is jealous and has taunted him.
- Beowulf desires recognition of the prowess of the Geats over the Danes of whom the monsters were not afraid
- Beowulf wishes to honor his race with his valor
- Beowulf desires to assuage any fears that Hrothgar may yet have for his warriors
- Beowulf wishes to heal the breach between the Geats and the Danes by symbolically presenting them Grendel's head as an offering of conciliation and friendship:
To both these people's peace shall be common,
To Geat-folk and Danemen, the strife be suspended
