Modern Day Beowulf and Grendel

I think it is very hard to find people to compare to Beowulf & Grendel because both of these characters represent certain traits or morals at a very extreme level, that are not very common today. Beowulf represents this hero who is fearless and proud. He is able to withstand any challenges that come his way with no worries whatsoever and a surprising confidence. There is no doubt in his mind that he can accomplish whatever he sets out to do. Beowulf stands for God, his family, and his nation. I think the closest group today that can compare to Beowulf would be the people in the army or law enforcement. These people courageously set out to protect their country and do not let the danger of their situation stop them from fighting. Paramedics and firefighters also show this great bravery when they save people's lives, similar to the way Beowulf does throughout the text. I don't think there is anyone that I would call a "modern day Grendel" because I don't fully understand this character and why he is the way he is, so I don't think it would be right for me to compare him to anyone just yet. Although today there are many people who commit insane crimes, I wouldn't say they are like Grendel because Grendel is very angry and commits all these crimes without really having a reason or motive behind any of it. Killing for Grendel seems almost instinctual and it seems that at times, he is more animal like than human because he does not think before he does these things and it doesn't seem like he really thinks what he does is wrong. I cannot really say that there is a modern day Grendel because I don't know if Grendel is really as evil as he is portrayed to be in Beowulf or if there is more to this character which I have not yet seen.
