To me, it's not about what the fox knows about the Sharingan users, or Madara, or the Rikudou, or Yondaime, or the Jyuubi (although he should know about all of these). It boils down to what he knows about Naruto. He's seen firsthand the strength of will Naruto possesses, and also the physical/spiritual strength that enabled a small child to house the Kyuubi without showing any signs other than a little ADHD and some funky whiskers. He also feeds off Naruto's pain, meaning he's more aware than anyone about Naruto's man-crush on Sasuke.
- First, I thought it was for his own safety, but lately.. it could also mean; Don't fck Naruto, because I know that dude and with my support, you're going down little sasuke
AND THE FACT, that without Naruto in Sasuke's life, sasuke would be nothing. He would be a lonely guy with no friends, no love from anyone. That's why he has to redeem himself in the end, to be whole again in his heart and trying to appreciate Naruto for who he his,.. the True Legendary Shinobi

Man... I don't even know where to start with this thread, everything's soo messed up...
