you guys seriously need to drop the expected views of a hero and accept that raito was the hero of deathnote. this story was about raito and his life from the point when he came across the deathnote to the point of his death. this fact makes him the hero of the story. if you want to look more into it, we had direct insight into raito's thoughts. it would have been a mystery what L was thinking if raito didn't anticipate him and if his thoughts weren't spelled out for us to see.
in this story, L and everybody that stood in raito's way were the antagonist's even though they were protecting justice. this is solely because they were obstacles to raito (kira), the hero of this story.
Actually, what "you guys seriously need" is to realize that hero is, in modern english, an alignment as well as a plot position. By the power of the english language, we have devloped several overlapping terms for the main character. "Hero" is one of them due to the main character traditionally also being the hero. If cooler wants to claim that Light is the hero by the protagonist definition, whatever. However, Light is, now and forever more, undeniably, factually, canonicly, not the "good guy".
Uryuu freaky, pale and geeky,
how do your powers grow?
"With gloves and scars and silver stars
and swords that I shoot from a bow,
yes, swords that I shoot from a bow."
i say that if the story was about L, he would have been the hero of death note.
but it was about raito, and throughout the story the author attempted to convince us that raito's views were correct. he was the hero of death note because without him, there would have been no manga to read at all.
True enough points... but at the very least to me and a few of my friends Light is not the hero, but he is the main character. The two do not go hand in hand, but everyone is entitled to see it the way they want to.
yeah... overanalyzing can ruin any good story
anyway.. i liked the ending
