Please answer the following question:

Question: What motivates Beowulf's heroism? Is he trying to prove himself in some manner? Is he trying to sacrifice himself for a greater good? To what extent is he altruistic, and in what ways might he appear egotistical? 

Please be sure to use evidence from Beowulf in the form of short 1-3 sentence quotations that you then analyze, or in other words, explain in order to tell us why the quotations are important and how they prove your ideas. Answers without evidence and analysis from the poem will not earn a high score.  NOTE: Write this answer in your own words and to express your own opinion. Do not go to websites and copy information, or you will earn a zero on this question. To earn credit for this discussion board, you must upload your answer to a Turnitin link, and to this discussion forum for your classmates to read.
