I wouldn't say he's my favourite but he is a definite favourite xd.
I have been looking forward to seeing how Kishi planned to deal with Sasuke. And Naruto's goal to become Hokage has been superseded by the "bring Sasuke back home to be a member of team 7 again" goal.
That and how badly he reacted to Gaara being killed and Sasuke being far more important to him.
I don't think Naruto will ever kill Sasuke or let anyone else lay a hand on him.
But back to your actual post; Sasuke is as of now in very deep trouble legally.
I think technically he's guilty of offences against all five ninja villages and the neutral Samurai country with the possibility of the Daimyo's of all six countries being able to veto any decision made by the Kage's (or Mifune) to pardon him.
Sasuke is so far guilty of (in the order they were committed); desertion, treason, use of an uncontrolled substance, assault, aggravated battery, attempted murder, resisting arrest - when Yamato went to the hideout -, (he probably took more drugs with Orochimaru and Kabuto).
Destruction of property - freeing Suigetsu, theft/looting - since Orochimaru did not give him an allowance where did he get the funds used to buy weapons from Neko Ba, breaking and entering x2 at both hideouts, conspiring to commit murder - to kill Itachi, *possible assault against Deidara*, animal cruelty, resisting arrest - running from Konoha.
Against Itachi - assault, aggravated battery resulting in death/murder, gross destruction of property and reckless endangerment - amateresu was Itachi's jutsu, arson, conspiring to commit terrorism/genocide - talk with Tobi.
Against Bee - terrorism, attempted kidnapping, reckless endangerment, arson, grievous bodily harm, aggravated battery assault.
Summit - conspiracy to commit terrorism, illegal entry (possible immigration issues), breaking and entering, assault, resisting arrest, attempted murder, murder*, terrorism, aggravated battery, assault, resisting arrest, conspiracy to commit murder (Danzo), reckless endangerment, wilful destruction of property, arson, grievous bodily harm, cheek - cheeking the police (authorities), attempted assassination, assassination/murder, attempted murder/grievous bodily harm, attempted murder x2, multiple counts of menace, assault (Kakashi & Naruto).
Some of his offences are or should be within the power of the Hokage to overlook - there is a possible issue that the Daimyo will have other ideas since she answers to him. The sand now has Gaara of all people as Kazekage so something should be doable.
I think his fraternizing with Akatsuki, offences against Kumogakure and the Samurai are the most serious.
That Jay dude was definitely killed, possibly the guy he interrogated with Tsukuyomi as well and obviously his attack on Bee. Daring to attack an irate Raikage, and the numerous Samurai apparently killed by him.
Since this was essentially an international summit, he became an aggressor to all 5 kages and the samurai.
Naruto is busy accumulating influence and has already made a name for himself as the hero who defeated pain etc etc.
He already has the Hokage on side, the Kazekage I'm sure will support him, he might be able to score points with the Mizukage for being a guy who might be slightly cute with a big helping of balls and integrity or something. Gaara being on side might also pull her and if a hopefully very obvious or reasonably obvious penitent Sasuke can squeeze out a few tears I think they'll have her.
The Tsuchikage doesn't really care and will probably go along with it. The Raikage will take some convincing I'm sure but they have at least a 0.1% chance.
The samurai's aren't really involved in their issues which I understand is why they had the summit there so I wonder how they'll react to a pardon.
Lol, I hope Naruto's been saving up for a lawyer .. xd
