Full summary:

After knowing the truth, all he wishes is for his elder brother to live. He'll die if that's what it takes. But his friends are always there for him. One among them saves him though. And Shisui's dream to watch Itachi and Sasuke to be good brothers together might fulfill. Since he is going to make everything right once and for all, he is peaceful. So Sasuke's attitude is mingling up with everyone like he was before the massacre.

DISCLAIMER: I do not claim Naruto.

REGRET IS A NICE THING!

1.

So at last Sasuke was able to kill his elder brother because Itachi was …erm Itachi. He let himself die in his foolish little brother's hands. That minute the great hero of the Hidden Leaf had completed his mission –the one he got from the council and the one he assigned himself to make his little brother a hero who avenged his clan.

The big battle has come to an end. Sasuke was so terrified for he had lost all his confidence that he would be able to take his brother down. His hands were literally shaking with fear of death. Although both of them reached their limits, Itachi could still kill the other Uchiha. Looking at his elder brother being surrounded by whatever the red thing is and approaching him made his heart race in his chest. He was holding his breath all along. Itachi was just a meter away from him. Sasuke was so frightened to run away to live or even make the slightest movement. Itachi's hands rose before his face. Sasuke had decided by then that he was sure to die. His brother was going to rip his head off with that hand of his or even worse that red giant was going to eat his chakra away. But to his surprise two bloody fingers of Itachi landed on his forehead, and was that the same old smile the big fat liar used to give him almost on a daily basis back then saying something along the lines of 'Sorry Sasuke. May be next time'?

"Sorry Sasuke. This is the last time"

He couldn't believe it. His heart skipped a beat. Then his brother hit to the wall beside him and dropped down falling flat on his face. He was dead. Sasuke was never this horrified, not even on that night of the Uchiha massacre. He stood like that for minute looking at nothing but into the space in front of him before shifting his eyes downwards to where his elder brother's body was lying lifeless. Then he closed his eyes. Random images from random times flashed in his mind.

The image of Itachi's face with tears on the night he left everything, and his Konoha shinobi headband tied to a side shining brightly under the moonlight.

Itachi carrying him home when he hurt his knee.

Itachi calling their clan 'pathetic', and his younger self hiding behind the door watching it without his brother's knowledge.

The very next scene of what happened followed after that. Itachi wielding his sharingan and then Mangekyo sharingan while glaring at him when he called out and said "Itachi, you have to stop".

Itachi poking his forehead with those very two fingers, and a very little himself muttering something.

Itachi holding Sasuke's throat tight against the wall and saying "You lack hatred".

Itachi poking his forehead with those very two fingers one more time.

Itachi kneeling to ground and coughing out blood randomly just before.

Itachi poking his fore head for the last time.

He didn't understand a thing. His mind couldn't process anything anymore. He dropped beside his brother and blacked out.

Now here he is deep in sleep in perhaps the safest custody of yet another Uchiha.

Sasuke woke up after like an hour or a half more. He wasn't sure if he was dead or alive. Anyway he thought, somehow he felt really fresh. After all he used up every last bits of his chakra which made him very exhausted. So he had a good and sound and peaceful sleep after so many years. Nice sleep, probably because I'm dead. Then he noticed where he was. He did not like the place very much. What a dark and dumpy place! He then let out a short sigh. Seems like the hell. Heaven would have been brighter. Tch. What on earth have I done to be in hell?! Oh right. How could I forget? I've betrayed my own village, what else? Then Itachi nii-san must be here too. His eyes widened for a moment. I thought I stopped calling him that.

He stood up and his body ached a bit. But it didn't bother him. After all he needs to know the reason why Itachi had killed everyone. It can't be true that his brother did that all just to test himself, right? He deserves to know the true reason at least now in their afterlife. He was about to move in that dark place. Then he heard someone speak and light up a candle.

"Your Hebi is outside and you're safe here."

Sasuke didn't know who or what it was exactly. The voice was new to him. A dead person's spirit like mine, probably. He did not give what the speaker said much of a thought. He kind of missed out the part that said 'your Hebi is outside'.

So Sasuke actually believes that he has somehow died and made it to the hell.
