He's never really been deceptive about the kind of person he is. He's openly been a d-ck since his introduction. And all I've gotta say about his relationship to Sakura is: she wanted Sasuke, and that's exactly what she got, not much more to it. Also personally, I like Sasuke throughout part 1. I disliked his d-baggery through all the Orochimaru and Itachi stuff in part 2. I started liking him again when he went full heel against Danzo. And then I loved his face turn at the end even though the war was atrocious and his turn at the end came more than a little undercooked. I can't think of a lot of other manga characters who go through as much change as he did throughout the course of a series. So, I find him interesting and I like him a lot. Sakura, on the hand hand, has always been unbearably obnoxious to me. Considering her behavior in this chapter, she doesn't seem to have changed. I will never understand NaruxSaku fans. I don't care at all that her life sucks. So there's more reason to not be bothered by the absenteeism and the two-timing which, again, I don't believe is true. I think Sarada is neither of their daughter and is adopted.
