I need to see more to help
Beowulf
is an epic written about a thousand years back and seeking revenge initiated a
clear cycle of revenge as I will explain below.
Grendel
the beast gets angry and attacks the Hall killing people, next comes Beowulf
who kills Grendel for glory as well as for revenge purposes. Grendel’s mother
attacks the kingdom to take revenge and in return killed by Beowulf, making it
clear that revenge is a never ending cycle.
Since in Anglo-Saxon tradition the setting of Beowulf,
revenge was something held in high esteem, in my opinion any other way would
not have seemed successful for the cultural values.
