Beowulf chooses to confront the dragon by himself due to a combination of pride, a sense of responsibility, and the warrior ethos that defines him. As a legendary hero, he feels compelled to protect his kingdom and its people, and he believes that tackling this danger alone will cement his legacy.
Moreover, Beowulf’s desire for glory drives his decision. He has already proven himself through previous battles against formidable foes like Grendel and Grendel’s mother, and now he sees fighting the dragon as his final act of valor. By facing the dragon alone, he aims to demonstrate his strength and courage, reinforcing his status as a heroic figure.
Additionally, Beowulf’s age and wisdom have shaped his understanding of leadership and sacrifice. He recognizes that as king, the fate of his people rests on his shoulders. Fighting the dragon is not just a personal challenge; it’s about honoring his duty as a leader. In a way, it symbolizes the transition from warrior to king, showing that even as he enters the twilight of his life, he remains ready to confront danger for the sake of his realm.
