The Mind Behind the Massacre

I don't own Naruto, Itachi, Sasuke, ect; and I never will. The weird thoughts in this are just that; purely thoughts. None are facts, which would have to be revealed by the Manga-ka, Masashi Kishimoto. I don't know anything more than the next Narutard.

Deidara was snooping through Itachi's room, trying to dig up any information that he could use to get back at the Uchiha. It was rare that he could do this; Itachi all too often burst in while Deidara was snooping, which all too often resulted in twenty-four hours or more of torture. In fact, Deidara was surprised Itachi hadn't burst in already. Deidara looked around the room once, making sure someone had not come in, when he saw it sticking out from under a pile of clothes. Carefully avoiding underwear, Deidara picked up the small, black clothed book. Is this…? Deidara thought. He opened the book to the front inside cover when there was a drawing of Itachi's Mangekyo Sharingan. Yes, it's definitely Itachi's diary. Deidara snickered. The thought of grown men having a diary, especially 'evil' grown men, amused him. He turned the page, hoping to find something that would help him get revenge on the Uchiha.

I showed Sasuke what I can do with the Sharingan today by hitting the dead-center of all the targets at the practice field. He was impressed and wanted to try, but he tripped and sprained his ankle. I had to piggy back him home. We passed the Police Force station, and I explained to Sasuke why the symbol was an Uchiha paddle fan.

Deidara could only think, This is useless! But he still continued to read.

Sasuke seems to try to get father's attention too much. He always tries to do what I do and tries to pass the same milestones I did. He knows father sees me, but father doesn't seem to recognize Sasuke all that much. He's starting to recognize Sasuke a little, but he needs to show more attention to him.

I don't care!!! He thought.

I've found out that to get to the next stage in the Sharingan, you need to kill your best friend. I'm trying to decide whether I want to pay such a price for the next level.

Yes, finally we get somewhere! Deidara thought.

Father is starting to pay a bit more attention to Sasuke, but only because I'm keeping to myself more. I want Sasuke to be noticed by Father, even if it means I wont.

I've also decided to kill Shisui.

Deidara was reading the diary as fast as he could. It was like an addiction.

I have killed Shisui and managed to make it look like a suicide. I think that I'm going to need to leave soon. Otherwise, the others may find out.

I hope it won't upset Sasuke to much.

The others are starting to suspect me in the death of Shisui. I don't know yet what I'm going to do.

That was I lie. I know what I need to do; I just wish that I didn't have to do it.

Tomorrow I am going to kill the clan.

Except Sasuke. I won't kill Sasuke.

I've done it. But I know Sasuke will want revenge. He doesn't understand yet. Perhaps he never will…

I don't care if he hates me, as long as he's safe.

Deidara felt an evil presence behind him. He turned to see Itachi standing in the doorway, a smoldering look in his eyes. Itachi then activated his sharingan.

A/N: Heh heh. It's done. Deticated to Cassie, the Ita fan-girl!

P.S. I've had a request for Kiba's Diary... That may be next, but... I DON'T KNOW MUCH ABOUT KIBA! T.T Help please! Tell me episodes about Kiba/ his past.
