Beowulf shows heroic traits in the conflict with the dragon as well as in the conflict with Grendal and the Troll Wife, but because of his self-serving intent, he is definitely not a hero. The heroic characteristics expressed by Beowulf in these two conflicts are fearlessness and courage in dangerous situations, as well as determination and loyalty for his people. Unlike a true hero, who would work his hardest for the good of the people in need, Beowulf's motives for fighting are very self-serving.
A celebration was held in the mead-hall to recognize the help the Danes were going to receive from Beowulf and his men. Beowulf tells the people in the mead hall that he is confident that he can beat Grendal. After seeing Grendal swallow a warrior, Beowulf knew that Grendal was a very big and powerful creature and he was determined to kill this monster that was cursing the Danes. Beowulf killed the monster the saved the Danes from Grendal's wrath. .
After Beowulf killed the creature, the Troll Wife (Grendal's mother) wanted revenge for the death of her son. The Danes summoned Beowulf because of his amazing victory over Grendal. When Beowulf met the Troll Wife he saw that she had the strength of a man and was very hideous looking. Despite how intimidating she was, he put on his armor and killed the mother of Grendal to help the people that depended on him. He received immense praise and adoration from the Danes, which was most likely his motivation in this conflict as well as in the conflict with the Dragon.
Beowulf showed a great amount of loyalty and determination in the conflict with the Dragon. When the fire-breathing dragon found out that one of Beowulf's servants had stolen a cup from its hoard of treasure that it had been guarding, it was extremely angry and destroyed one of Beowulf's mead-halls. After hearing of this incident, Beowulf (who had been pronounced king 50 years earlier) headed out with eleven of his men in search of the angry dragon.
