I could say that we see throughout the anime Raito gradually turning into Kira. But that is not what happens. Raito is already a born killer, he was ready when he finds the Death Note, he only lacked the means to carry out the murders.
L is the balance in the scales of justice that is created in the anime by Kira, he as well hunting and hunter by Kira.The plot becomes increasingly tense as Kira and L are one after another, with its climax with the death of L. And from there, it leaves something to be desired, it's like Kira lost a little interest in his ideals.
The loss of focus of Kira's not something that would seriously damage the anime, because that's room for other characters like M and N.
The loss of focus Kira is not something that would seriously damage the anime, because that's room for other characters like M and N may intervene in the plot, which will seal the tragic fate of Raito.
Thus, anime is a great site for those who enjoy suspense, mystery and police action. With its remarkable characters and worked very well, it makes us paranoid with their finely calibrated events calculated by L, M, N, and Kira.
