In Beowulf, why is it that Beowulf is considered a round character?I'm writing an essay where I have to support that claim, but can't seem to see...

Beowulf is round, dynamic character because he is the
poet's epic hero who changes greatly throughout the narrative.  He is full of paradoxes:
he is both pagan and Christian, blood-thirsty and generous, immortal and
vulnerable.

Beowulf begins as a young, proud hero who
defeats Grendel with his bare hands.  Then, he swims to Grendel's mother's lair and
kills her.  But, with each battle, and as Beowulf ages and his opponents become
deadlier, Beowulf must rely on weapons and armor to kill them.  He must use a magic
sword to slay Grendel's mother and heavy armor to slay the
dragon.

By the end, Beowulf becomes a victim of the cycle
of revenge that made him great.  Beowulf, once the idealized, indefatigable epic
warrior, becomes greedy for treasure and dies trying to protect his
status.
