When Team Hebi is formed, Sasuke states that the team only has one goal: to kill Itachi. But what are Sasuke's other goals? Earlier on, Suigetsu tells prisoners that they are free and to spread the word that Sasuke is going to bring "peace and safety to the world". It's not clear if Sasuke instructed him to do this, however.
So, if Sasuke approved this message, what does he mean by it? After killing Itachi (assuming he's successful), how will he bring peace to the world? My theory is that he will attempt to eliminate all the bijuu. Akatsuki has already done most of the work in bringing the bijuu into one place (the summoned statue), so Sasuke just needs to figure out how to destroy it along with the bijuu. This would certainly bring peace to the world, since from other sources (for example, Chiyo) we know that the bijuu were used in the ninja wars as weapons through the creation of Jinchuuriki.
If true, this would also set up a confrontation between Naruto and Sasuke. As the strongest Jinchuuriki, he would have to be killed (or the Kyuubi extracted) for Sasuke to meet this goal. Thoughts?
