What is the reason for the tragic end of the hero beowulf?

Beowulf's tragic defect is the reason and his tragic flaw is his hubris. He was so arrogant that he overestimated himself and thought that he could beat a dragon alone. This pride drove to his release.

Explanation;

After Beowulf displays the ruler of the Geats, one day a robber invades and disorders a barrow where a dragon was resting guard to a wealth. This provokes the dragon and it begins to spit fire on the people of Geats. Beowulf continues to fight this dragon. Though he kills the dragon, the dragon bites him through their fight, the venom from which witnesses to be deadly, killing him. This is how the hero appears with a shocking end.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
