Compared to Beowulf, there was “no greater warrior more worthy of a kingdom. Yet they found no blame in their own friendly lord, their gracious Hrothgar.” Why may Beowulf’s success be a problem for King Hrothgar?
A king is supposed to be a leader and in some cases "the strongest of them all." If Beowulf is able to put a stop to the attacks Hrothgar couldn't, he may seem less unfit to severe as king compared to Beowulf.
