Answer:
We can feel a certain empathy for Grendel.
Explanation:
Although Grendel is a bloodthirsty and extremely violent monster, we can feel a certain empathy for him, as readers, if we analyze that much of his showmanship is the result of humanity's rejection of him. Grenndel lives in filth and chaos, because humans do not accept it and present themselves as a threat and competition in their territory and therefore, as a wild animal attacks to defend itself. In this case, we can say that Grendel is a villain because of humanity's lack of empathy and solidarity.
