I don't think Sasuke Uchiha should die. He really isn't a bad guy. Sasuke's family was killed by Itachi under orders. (don't blame Itachi). Sasuke, not knowing this, losing everything, decided he had nothing more to lose, decided to take revenge on Itachi. Sasuke only focused on revenge. I doubt he understood that he had people who loved him. Fueled by hatred, he sought out power, aka Orochimaru. He then was able to kill Itachi. Feeling complete until it was revealed it wasn't Itachi's fault. Angry at himself for loathing and killing the only family he had left on this Earth, he went and killed Danzo, who was one of the poeple to ordered Itachi to kill the Uchiha Clan. After killing Danzo, slowly losing his mind to the mental and psychological pain we went through, he wants revenge against the Village that betrayed his family.
I first thought Sasuke was an ***hole but once I read about his past, I understood, his pain and I understand why Sasuke did the things he did.
I think Sasuke is just a victim who has lost his way.
