The Shinigami's Touch
For as long as Naruto's been alive, all alone in a rundown building in the Forest of Death, he was able to see the wayward souls of the dead. And, he can not only see the souls of the dead, but he can also interact with them. Until the Kyuubi's meeting, Naruto never knew why he could see dead people and others cannot... but then, he figured, it was a curse from the Shinigami. After all, he learned the seal on him was made with the help of the Death God which took the life of the Fourth. But nonetheless, Naruto did not let it hinder him, even though, growing up, he was always haunted by the dead souls who believed him to be the cause of their death. And of course, that also included the Uchiha Clan whom been murdered by Itachi (which in self defense, he killed them because he was loyal to the village than his own clan). Naruto...
Well... Naruto didn't develop his darker powers well until he turned seventeen...
But by the time he turned seventeen, his soul had already become consumed by the black energies of the Death God.
In other words: his soul was damned from the beginning...
And the world was damned the moment Konoha wished for his death after his birth...
