Explanation:
The poem Beowulf has a Christian background and the descriptions of Grendel are things Christians can easily identify with albeit in a negative light. He is first described as a fiend from hell. A fiend is an evil spirit or demon. He is also described as notorious, meaning that he was known for something bad. He is compared to Cain, a man known by Christians as having taken his brother's life.
Grendel is also described as a sinful creature, grim and greedy. His attribute as a Cannibal was also described when the poet said that he ate a lifeless man. All these words and phrases denote Grendel as a fearsome creature.
