That shinigami is the personification or shinigamication if the author or the story writter I think... I can be wrong though..
Let sure is brilliant.. while Kira is just in a spiral of emotional inbalance
@STING380,but thats not justice is it? if you kill L, you're killing an innocent man,and thats the beauty of this manga, it's all subjective. and depends on the reader whats its good or bad.
Yeah, I guess that the sudden heart attack could be a hint but to believe that his first-ever victim was a murderer from Japan. He could have been wrong too, right?
But nonetheless, L is really getting a deep investigation into the case right now.
