After Grendel begins attacking Herot why is he allowed to continue attacking?

After Grendel begins attacking Herot why is he allowed to continue attacking?

Explanation:

The most obvious motive for Grendel's attack is envy and a sense of exclusion. He hears the laughter in the mead-hall, hates the Danes and their merry-making from which he is excluded, and resolves to kill them. Even slaughtering thirty does not satisfy him and he returns night after night to drown his misery in blood.

the answer is definitely option c. "sonnet xxxi best illustrates the division. in the octave, the poet observes that the moon is in love. in the sestet, he gives his reaction to the fickleness of woman's love."

showing or having an insensitive and cruel disregard for others. (so basically being heartless)

hope this : )
