I agree with everything except your conclusion.Sasuke's life was ruined by the elders,and more importantly itachi who didn't kill him when the time came.He was screwed from the beginning,but every man must take his consequences,and sasuke kept looking in the past instead of the future where a lot of people where ready to help him succeed.From the third hokage all the way down to his team,who understood his pain and tried to help him,but unfortunately, sasuke was not strong enough and his jealousy of naruto grew out of hand.
He desperately wanted power,at any expense,so he embraced the darkness and hatred inside of him(helped by itachi,oro and madara).
He is not only a criminal.but a murderer,so he should be executed,but too much energy has been used on sasuke, in this series, too him not get some sort of resolve.Not by coming back to konoha,unless in a coffin,no he will get rid of the hatred with the help of naruto and either die as a hero or become a less emotional villain,perhaps even a vigilante.
A crime is a crime, so no sasuke is not innocent.
