Half of the cast of Naruto should be imprisoned/executed. Kabuto for his war crimes, not to mention abandoning his village and the countless crimes he must have carried out for Orochimaru.
Orochimaru was an S-Class criminal who killed thousands in cold blood, usually for his experiments, and who is responsible for the death of the 3rd Hokage on top of abandoning his village.
Sasuke went rogue, committed who knows how many atrocities in the name of Orochimaru, made himself a traitor when he launched an assault on the summit, branded himself a member of Akatsuki at the height of its operation, assassinated the acting Hokage (Danzo), plotted once again to kill the five Kage and make himself the world leader.
Not to mention that basically everyone who ever served Orochimaru or Akatsuki should be sentenced to death.
But this is a child's manga, after all.
