Modern Day Greed

Throughout history, human beings have spread knowledge and understanding down through the generations. We have slowly improved our ability to go through our life in an effective way over time.  However, we haven't made as much of a leap as we could go.  Greed is largely the reason for this. Radix Malorium Est Cupiditas. If we weren't so concerned about our self-gain and material value, then we would be much more advanced. Due to greed, thieves steal, envious people murder, and so on.  The slower rate that human generations work together is all due to the self-concerned actions. These actions wouldn't exist if greed wasn't so convincing.

Truth

In the book "Grendel," the alternate perspective can change the way people view the story and it's characters.  Contrary to the classic story, "Beowulf," humans can be considered the wrongdoers rather than the murderous Grendel, in the John Gardner version.  The "truth" of this story is difficult to determine.  If the truth is based off of whether or not Grendel is in the wrong, then I believe he is not.  The simple nature of human beings was responsible for his unfortunate childhood, causing him to become the way he is.  If the truth is based off of what happened in the story, then this is the truth. Human existence is always ridden with things like ignorance and false judgement of others. Because of it, Grendel decided to take a path that he thought was righteous, ridding the world of humans in order to save everyone else.  Beowulf however, came with the notion that Grendel was murdering for simply no reason at all. Therefore he slayed him for a reason he believed was righteous.
In conclusion, I believe neither Grendel, nor Beowulf was in the wrong. Regardless, things can simply happen in the world. Sometimes, bad things happen to good people, and a lot of times, it is no ones fault.
