1. Sasuke abandoned the village, but this is inevitable anyways.
2. He joined Orochimaru. Alright I'll give you this one.
3. Attacked the Gokage summit, although I believe he was attacked first and not only that, the Gokage tried to kill him. If he managed to kill all Five of them it would have simply been self-defense.
4. Attacked Killer Bee. It was wrong, but the Hidden Cloud is hypocritical for complaining after trying to kidnap a little girl so they could have the Byakugan for themselves.
5. Trying to kill Sakura and Kakashi. If I remember correctly, these two tried to kill him first, self-defense yet again.
6. Attempting to kill the Five Kage? I don't remember him trying to do that, but he did admit to the fact that he wanted to do that.
7. Killing Danzo. If anything we should be thanking Sasuke you ingrates, if it hadn't been him, someone else would have done in Danzo.
8. Trying to kill Naruto. True, this is punishable.
