Question: 1. what is the difference between beowulf and unferth as warriors?
Answer: Unferth is presented as contrast to Beowulf, providing a glimpse of a poor warrior in contrast to Beowulf's good warrior. Unferth is boastful, just as Beowulf is, but unlike Beowulf Unferth lacks the moral courage to back up his boasts (and unlike Beowulf Unferth never does anything to stand against Grendel).
