Sasuke's crimes aren't big enough to be forgiven? What? He helped start the war, he attacked the 5 Kage, he murdered dozens of samurai, he joined a terrorist organization, attacked a foreign nation, and he tried to slaughter the 5 Kage and take over the world. Killing those samurai is just as bad as killing anyone else in the series. Sasuke deserves zero levity for his crimes.
Edit: Just to put this in perspective, Sasuke had an active hand in reviving the Juubi. Everyone that died in the war because of the Juubi, Sasuke holds partial blame for their deaths. He killed Neji just as much as Obito did. Sasuke is partially responsible for tens of thousands of deaths.
@WhyDoIWatch: I get that you like the Sasuke character and laid out every excuse there is for him. The biggest thing with me is that Sasuke no matter how tragic his past was, made the choices that turned him into the thing he swore to avenge. A murderer! Like AHK noted he killed samurai that he had zero affiliation with. They just happened to be in his way. If any of those samurai had children is it okay for them to seek out Sasuke and try to kill him or anyone else that gets in their way? Murder is unforgivable. Plain and simple. There's an old saying "before one embarks on the path of vengeance, be sure to dig two graves." That should have been what happened to Sasuke.
I dont understand why some people think sasuke crime is not big enough to be sentence to death. His family and clan was slaughtered and killed by konoha high ops but what did he do? he plan on killing all konoha citizen. That is beyond crazy , killing high ops/elder who responsible is totally ok but killing everyone in the vilage?. What he do is just spreading chain of hate. He wants to kill gokage just so he can establish his new system and ideology. He thinks want he wants is more important than peoples life. Thats just insane this guys is physco and abusive. Sasuke should have died there is just no positive reason for him to stay alive.
