Whoot! this is great! Real deep :D

It does make sense. And the way you wrote it struck me as realistic and gritty. There is nothing beautifying or tender melancholic about this, it is short, to the point and leaves you behind with a frown.

You leave a lot unsaid, which I consider to be good because it makes the reader question things. There is something delusional about Naruto's thoughts -- blindly optimistic -- that makes me question Sasuke's motives and make me believe, that in the end, he has become like Itachi. I believe that he wished to die (the creepy smile on his face reminded me of Haku), that in his death he found something akin to peace.

I think you did a good job portraying Naruto’s horror and in its simplicity, I think it was more striking.

s what he say when his mind was given back control.

Replace “say” with “said”.

“… had once filed by simply staying alive…”

I loved this sentence, but there is a little error: “filled” is the word you’re looking for.

Wow.

That was awesome Hoshi! It made sense to me, so, no worries about that. Oh, I love the ending, even though it's sad...

It does make a lot of sense :) I liked it a lot, although the ending is so sad. Good job :)
