Answer:
Because revenge causes more problems that lead to more anger. Empathy leads to peace
practical
Even though Grendel seems as though he's being harsh by eating the exile, he is actually being practical. He says he tries to do things that are more considerate like befriending or ignoring him. However, since the exiles were treacherous, eating them is the most practical solution.
This is indirect characterization because it SHOWS, rather than tells.
Here are two examples:
Indirect: Erica stomped her foot and flew out of the room.
This shows that she is angry, rather than just tells.
Direct: Erica was so angry she stomped her foot and flew out of the room.
This just tells you she's mad.
