[action]
[Sasuke just waits until he hears his younger self speak up again]...It was the one thing he couldn't bring himself to do.
[He just take a deep breath, trying to calm himself down. Even retelling this was a task in itself but he couldn't keep it from himself. He hated that he found out just moments after Itachi had died even if that's what he wanted for himself, it wasn't what he wanted. From all those years of hating him, it still felt very surreal, all those years spent training to get strong enough to kill him-- all based on a set of lies forged to get that one particular end result] Before he left, he asked the Third Hokage for our safety, to protect us from Danzou and the elders. He even threatened them that if anything happened to us, that he'd expose the truth to the other villages.
If it were up to him, we would never find out about it at all-- that's why instead of telling us the truth that night, he convinced us it was all his doing and gave us revenge as our goal because he wanted to die by our hand. He thought that if we did... to the rest of the village, we'd be a hero while restoring the honor of our clan. [It took a lot for him to say all that, but there it was-- the truth behind what happened that night]
