And even excepting Kakashi, there's no reason for there to be any attachment between any of them. Naruto and Sakura actually knew him--who he was before he became ruthless and selfish and, I venture, a bad person--long enough and intimately enough to care about him and form bonds, and for him to form bonds with them. He was like a brother to Naruto, and I do think that Sakura really loved him. And, as I see it, he cared for them too.

Anything you could argue for Suigetsu and Karin pales in comparison.

Him asking Karin how she was kind of pissed me off, because I can't see any reason why he should care. These people don't know really know him and I don't think she sees beyond the superficial with him. Plus, he's already demonstrated how far he's fallen--why does bastard!Sasuke suddenly give a shit? It cheapens the bonds between Team 7 and it bugs me.
