He's basically cast away all emotions so he can devote 100% of his interests towards the sake of Konoha.

What's selfish are people like Naruto.
Konoha doesn't want Sasuke back, he's a traitor.
Sasuke doesn't want to go back to Konoha.
So for who's sake is Naruto trying to bring Sasuke back for? Nobody but his own and Sakura's
For Konoha's sake. It's huge trouble if Oro transfers to Sasuke's body.
