True,but you have a reason to like him.Hes suck a ambicous person believing he is doing the world good by ridding of criminals.You start to grow attached to him. Thats why it was so sad :O
I think, that light being so smart during the anime and so stupid at the end was the worst. Why would the guy with the Shinigami eye need the full deathnote ? Light could have said instead to keep a page somewhere, like a pocket, and he would have won, that bothered me so much and besides ending ''good'' I disliked it
