Disclaimer: I do not own Naruto.
Warning: Spoiler, episode or maybe 300 and 400 and up I think… I don't remember and too lazy to check.
Sakura,
I am in the Akatsuki with my new group. I am helping them, but I am assigned to get the eight-tailed, not Naruto. I might need to help Pain to get Naruto. But it doesn't matter, I will still get Naruto.
Pain promised me one of the Jinchuuriki to make me strong enough. I don't need to tell you what had happened between me, Itachi, and Tobi; the leader of Akatsuki. But what happened then had made me join Akatsuki.
I can't answer whether I hate you guys or not. You know the answer.
Yeah, it is shocking to hear that you're strong now. I wish to fight you one day… soon. This Sai guy, I remember him… you're in love with him?
The new Team 7 sounds very nice. You're happy with your current team and I am no one to judge.
Karin is a slut. She's worse than you even though she's already strong when I first met her. I wish to fight Naruto soon. I will defeat the eight-tail and I will defeat Naruto.
I will revive my clan even though Konoha might burn to the ground when I get there. Whatever happens, I won't change my mind. Good luck to us both, and to everyone in Konoha. Just pray that Pain softened up when he get there.
I don't know whether this means anything to you now. But I realized long ago, before I left Konoha for Orochimaru that I wanted to protect you. I know that's the reason I refused to bring you along. Other than you are weak back then and would be a big burden for me.
I'm sorry if I ever made you and Naruto suffers, but I have more important things in my life than just care for the both of you. Now, nothing could be stop. All of you can only pray… and I won't pray along. I am arrogant, but I also won't change that. I'm sorry.
P.S. I Love You.
Sasuke.
