The only reason Nagato used it is because those people died by his hands, Sasuke was on the side of the alliance in the war, he didn't kill them. Ok, but why he didn't revive Itachi (he loves his brother, and he wanted to revenge for him) and Sasuke "killed" Itachi (Itachi die in battle with Sasuke).
