Oh the Uchiha and their love, it's so touching. 
Indeed, it about his love. His love for Itachi is what makes him sacrifice everything. The chapter itself it's called 'Sacrifice'. I don't think he cares 0% about them. But he cares 100000000000000% about Itachi. He's cold. He put everything in a balance and he doesn't doubt.
But don't take me wrong, even if this is true, that doesn't mean i support SK and SS as couples. Because, they can be sacrified.
Sasuke went from Zabuza last moments to Zabuza when he trained Haku as a shield.

I'm just trying to be objective about what Sasuke's character means. I'm not trying to excuse him. I'm trying to explain what it is. Moral has nothing to do with it.
