I don't know if it's just babbling, but nothing about that statement leads me to believe he has deviated from his original goal. He still wants to break Sasuke's hatred and have him return to the village. If he still wants to break that hate and not bring him back what does he want to do? Kill him? Die with him? I still believe Naruto that would not consider it "saved" if he has to haul a corpse back to the village, especially if Naruto delivered the killing blow. In that case, he still died because he gave in to his hatred. He'd just realized he was a dumbass for doing it.
Realizing he was an idiot for pursuing it is not saving him from it. It would just drive home the point that revenge is bad, something already established.
I don't think what he says is a resolution to no longer bring him back but a realization that if they both go at each other they will kill each other not that his objective has become to end his life.
Naruto could not kill Nagato who actually did much of what Sasuke says he will do and he could not kill him. He will not be able to kill Sasuke.
Nagato did die as part of his redemption, but Nagato died because of an act he took on his own.
