They are already friends. At least, they have a bond connecting them in some way, according to Naruto. I believe Sasuke feels the same, but he doesn't show.
no, not so far in the anime
There is no "they"...only Sasuke kills Itachi. And, no, Sasuke is not friends with Naruto.
there best friends
I think so because before sasuke left he said he considered naruto as his best friend.
yes they are
Since the academy and they still are. Although Sasuke and Naruto don't really admit it. They really are still friends no matter how much they fire off punches.
As of now, no. But, the series is ongiong.
No, not according to what is so far revealed.
Shippuden hasn't ended yet, but so far, no. (Although Naruto still thinks of Sasuke as a friend, of course.)
no because so far in the manga and episode sasuke is bad i'm not saying he will always be evil
I'm not completely up to date on Shippuden but in reality I think Sasuke still thinks of Naruto as a friend. Sasuke isn't cruel enough to completely sever that bond.
because they love and like each others
No. Naruto is truly devoted to his friend. Naruto, since he never has known his family, imagines that Iruka is like a father, and Sasuke is like a brother. This is all in chapter 229, and the chapter title is The Bond...!!
