What was Beowulf's riskiest risk?

Beowulf is an early medieval text that survives in just one manuscript: Cotton Vitellius A, also called the Nowell Codex of the British Library. It also contains Wonders of the East, Judith, and Letters of Alexander to Aristotle, as well as other Old English works. Beowulf is one of less explicitly Christian works in the codex, though it is still Christian.

Beowulf risks death for glory three times in Beowulf. His first risky action is coming to save the Danes from the monster Grendel, who sneaks into Heorot at night and devours warriors. He knows that he could perish, but would rather die a glorious death than live a long, unremarkable life. Beowulf's second significant risk occurs when he hunts down Grendel's mother, who has decided to take vengeance for her injured, dying son. Beowulf dives into a deep lake to seek out the mother and kill her. Beowulf's final great deed is his attack on a fire-breathing dragon that is terrorizing his people. Beowulf manages to kill the dragon, but dies in the process. He thus gains glory and is immortalized forever in a barrow on a sea cliff and in the Beowulf poem.
