Final answer:
Beowulf is initially wished to be king by the Geats following Hygelac's death, but he refuses out of loyalty to the royal line. He emphasizes the importance of proving one's character through leadership, highlighting the weight of such a responsibility. Beowulf accepts kingship only after the rightful heir dies.
Step-by-step explanation:
Following Hygelac's death, the people and Hygd wish for Beowulf to be king. However, Beowulf refuses the offer of kingship out of loyalty and respect for Hygelac's heir, stating his commitment to the rightful succession and the importance of maintaining the royal line. Beowulf articulates that it is challenging to truly understand a man's character and intentions 'till he be proved by exercise of power,' emphasizing the significance of righteous leadership and the responsibilities it entails.
Eventually, Beowulf does become king after Hygelac's son and rightful heir dies. This demonstrates Beowulf's noble character, showing he is not eager to seize power but rather considers the greater good and the proper lineage before accepting the throne.
