You're barking, seriously.
But it's not strongly impossible. If he does die, I doubt it would be against Madara though. Sasuke IS the final arc of the series, after all. 50/50 both ways.
No I will not be upset. He is truly the most remarkable character of the series. Without him, I finally have an excuse not to be upset about the series coming to an end. I used to read the Manga for the story. But I honesty continued only to follow his, and I can assure it goes the same for other Sasuke fans. Many people will disagree. But try making a powerful connection with something, and try taking it very lightly. Can't do it. For someone to REALLY appreciate Sasuke, they have to feel these ways. It can be held accountable that he is relatable. A bond with fiction can be its own reality, trust me. If he "dies" I will go to every rigid end to prove this point. Regardless of what Anti-Sasuke's say and think, he is pret-ty f*cking important. And he is admirable and very much a masterpiece.
