Well as of the current manga, around chapter 400 to now, he hates all of Konoha and especially the elders. After Madara reveals the truth about what they did to his family, and his older brother, Sasuke hates Konoha entirely.
sasuke wanted to go back to konoha, but he switched where he had wanted to go... which was the meeting place where all the kages were meeting, so we still dont know whether he will come back or not.
Eventually, Naruto does finally find Sasuke. However, he is unable to convince him to return to Konoha.
all of volume 65 (chapters 618-627) is about that, but he starts to go back to konoha at chapter 618
yes
No.
Yes, he has returned to Konoha to learn some of the secrets behind the Uchiha clan, from the mouths of the old hokage themselves. He has declared a wish to be hokage himself but is currently part of the alliance against Obito and Madara.
no. naruto will probably kill sasuke or bring him back to konoha, i don't think she needs to look for him.
yes when they are adults
Actually Pain destroys Konoha but Sasuke does attack konoha.... he eventually fights Naruto and Kakashi and also sasuke loses his vision.
No, Sakura does not betray Konoha. She pursues Sasuke and pretends that she wants to go with him, telling him that she will betray Konoha to go with him, but it is a ruse to get close enough to kill him.
yes
