Why Did Beowulf Follow The Want Of Grendel's Mother?

The movie entitled Beowulf gave me a mixed emotions of angry, shock, amaze, happiness and realization that things happen now is already happen ever since and I don’t know how I survived with those emotions I felt for almost or more two hours I guest. Actually at the beginning of the movie, I was shock of how they celebrated, though I know at that time people celebrate like there is no tomorrow, sing and laugh out loud, and drink liquor like a water except for the things man and women do that hard to absorb (SPG). But as the movie plays, I was amazed of what they have, kingdom, king and queen, lovely people although some are not, Beowulf that has an extra ordinary strength and beautiful place.

Beowulf is a brave, powerful, intelligent man and has an extra ordinary strength that enough to kill the mother of the evil. I thought he will kill it but I was wrong, actually all of us I guest, but I ,we are wrong because he just let that evil victim him and let the history repeat and it destroy the kingdom and lot of people sacrifice and suffer again. He did not kill the evil but he let the evil to kill his goal, to kill the monster and end the cause of the problem that destroy the entire kingdom and because of that mistake, the problem get even
Beowulf become evil in his own way and choice, but then at the end he still do the right thing, he sacrifice his self and gave all his strength to save the kingdom, the people, and his two wives. Though evil win in the first part of the movie, still in the end, good win, Beowulf win, win on his way. In reality we are like Beowulf, we are all inborn good and we have are goal to our life which we want to achieve but because of those evil or bad people in our surroundings, we let them to victim, influence us and break our goal in life. There are two types of people we have in our surroundings, it is just us to choose which of them will let us to win to be part of our life, part of us and we want us to be and if we did a mistake, still the do a right things to solve and end the mistake we did, like Beowulf did in the
