Before he became a member of Akatsuki, pre Shippuden, Hebi Sasuke, he wasn't. So he left the village at 16. Big deal. It's not like he was doing anything wrong or harming anyone. He just wanted to get stronger so he decided to leave a nursery and enter the warzone. They are ninja's. It is one of their responsibilities to get stronger. If he never left then he would have never been able to fight Itachi.
He did the world a favor with absorbing Orochimaru. Even if he did join him, it's not like he participated in his experiments. In fact, that was the very reason why he absorbed him.
When Sasuke fought Deidara, he did the world a favor with Deidara's suicidal attempt. Deidara is a known terrorist that nukes unknown territories with his explosives. If Deidara never died, then he would have still been bombing unwarranted residents.
Sasuke's "crimes", as people like to call it only started when he tried to capture Bee. Did he try to capture Bee? Yes. Did he actually succeed? No. So what exactly is the problem again? I see very faulty logic in blaming Sasuke for trying to kidnap Bee when in fact the Cloud has tried to do this same notion with Lady Hinata in the past, but the Leaf let it go and said forget it. Why aren't the Cloud considered criminals? Is it just because it's Sasuke? The Cloud only got angry because their leader is an uncontrollable hot head who cant control his temper. As soon as he heard the news of Sasuke kidnapping Bee, he called for a conference with the other Kage. Bee is still alive. Bee is not dead. He is still alive and breathing. Better alive than dead.
When it comes to the samurai, Sasuke was at fault here, but Sasuke explicitly warned them not to interfere. Samurai have no place to be fighting with ninja's in the first place, so if they want to risk their lives fighting a fight that they can't win then that's their own problem. Did Sasuke intrude into the conference? Yes. Did Sasuke walk into unwanted territory? Yes. Was Sasuke trying to kill those Samurai? No. Sasuke was only after Danzo, but everyone else decided to butt into something that didn't concern them.
And then we move to Danzo. Some people think that Sasuke's actions towards Danzo are trifling and menacing, but who in this ninja world actually cared for him, besides Sai and his other fodder followers? Even the other Kages and his own Leaf peers didn't trust him. Danzo did some heinous crimes in the past and Danzo's death should be a light to the world.
Sasuke also announced that he was going to destroy the Leaf, but did he do it? No. Sasuke announced that he was going to kill everyone in the Leaf who smile on his misery, but did he do it? No.
There are many things that Sasuke said that he was going to do or try to do, but he never actually did them because of changed events. If I lived my whole life searching and trying to get stronger, just to kill a certain guy that caused my dispair, but then I turn around and find out that he was actually a good person and just cared for the village and me, do you honestly expect me to go back to the very same hometown that plotted my brothers demise? The Leaf village and the elders are selfish and Sasuke knows this, and that's why he wants to change it.
If Sasuke does get punished for his crimes then his only crime would be killing those fodder samurai, but when you look at the concept of them being ninja's and fighting everyday of their lives, killing some insignificant warriors shouldn't be much of a concern, considering that past warriors between neighboring nations would involve the killing of many people. If you want to call Sasuke a criminal for killing some Samurai; then you should also call those ninja's that have been fighting in previous wars killing other nina's criminals as well.
Sasuke was not always like this and after his talk with Hashirama he decided to protect what his brother wants to protect. You are basically calling him a criminal and harping on events that have happened long before he changed his ways of saving the world. I guess saving the world from the biggest threat to ever exist in NV completely pales to killing some stupid fodder samurai who were destined to die anyway. Gaara also killed many innocent people. Is he a criminal? Of course not, because he's not Sasuke.
