In Part II, Sasuke sees little change from his personality and mindset at the end of Part I, still craving power above all else. His lust for strength is such that, during his reunion with Naruto and Sakura, he claims to be willing to give his body to Orochimaru if it means killing Itachi. Sasuke has at least changed to a point that he no longer cares for his former teammates' well-beings, being more than willing to kill them since neither is of any use to him. His relationship with Orochimaru shows a similar lack of loyalty, as during their time together he applies no honorifics to Orochimaru's name, is somewhat rude to him, and does not express his allegiance with Otogakure by wearing a Sound headband. Of the loyalties Sasuke has, the only one he displays is that of the Uchiha clan, the symbol of which he wears on his back collar. Despite this lack of allegiances to those close to him, Sasuke seems to be unable to bring himself to needlessly harm those he has never met before, and makes it a point to prevent their deaths when possible. He's also known for being the most gayest character in Naruto. Commonly called Naruto-sexual.
