Most fundamental human qualities are displayed by Grendel. He was an intelligent monster with the irrational thoughts capability. He shares the lineage with the human being, as being a descendant of the biblical Cain. Very little separates him from other human beings due to his nasty eating habits and awful appearance. Moreover, he accentuates the inherent violence of man. This highlights his philosophical quest is of human-like. By the wasteful war he feels disgusted on the other hand he is easily upset and cautious.
Grendel's relationship with the humans is characterized by the emotional response to the concept of community. Grendel is frustrated with the world he is living in, the animals that surround him are dumb and undignified. Further, that his mother is driven by the emotional instincts. Therefore, Grendel is trapped in his own world where he performs one-way communication by talking to the sky or air with no response.
The human who resembles Grendel in many ways, most painful refusal comes from them as they fret and disgust to share any meaningful conversation with Grendel. Yet Grendel, so close to humankind he is kept at a distance. Grendel's tragic status is underscored by the Shaper's Tale of Cain and Abel ( two sons of Adam and Eve).
In the Danes, Grendel instills horrendous fear. While the warriors sleep at Herot he attacks them and haunts marshes and moors. He feeds on human flesh and drinks human blood. Grendel has "Powerful jaws", "Swift hard claws", and "Great teeth" along with magical powers. Hence, he was emphasized as a horrible monster who was filled with blood lust and hatred. Therefore, Grendel is a monster whose inner self-resembles with that of humans and his physical appearance prevent him to enjoy the companionship and comfort of the civilization.
