Final answer:
Many of Beowulf's wise people likely did not regret his departure because they understood his duty to help King Hrothgar and viewed it as an opportunity for him to demonstrate his valor and enhance his legend.
Step-by-step explanation:
In the epic poem Beowulf, the lack of regret from many wise individuals when Beowulf leaves his homeland is not explicitly explained. However, it can be inferred that these wise people understood the great deeds that Beowulf was set out to do. Beowulf was determined to aid King Hrothgar and the Danes in their struggle against the monster Grendel. His reputation as a warrior and the sense of duty towards helping others in need could be reasons why his wise men did not regret his departure. They likely saw it as an opportunity for Beowulf to prove his valor and to enhance his legend. Additionally, it shows their trust in his abilities and the honor of fulfilling such an important mission.
