I think that Sasuke wants to be recognized by his brother just as badly if not more then he wants revenge.
He is following his brothers plans for him almost perfectly. He told Sasuke to live and gain power through hatred and that is exactly what he did by leaving Konoha and his friends. Sasuke gained a small victory by not killing Naruto but I would still say he is being his brothers puppet and gaining power the way his brother wanted. Itachi's whole plan for Sasuke was to seek revenge and carrying that out is partially because he wants recognition.
To further illustrate my point look when Itachi meets Sasuke again. Sasuke tells Itachi that he has been doing just as he was told, living to kill him and hating him. When Sasuke wakes up he is most upset that Itachi was after Naruto and not himself. His jealousy from before becomes even worse. He wanted his brother's attention and recognition but instead Naruto got it. When he wakes up he doesn't worry that his brother is trying to kill his loved ones again, instead he just gets mad because Naruto is getting the attention.
Gaara, after his fight with Kimimaro, says that people can't always choose who their special people are. I think that even though Sasuke does hate his brother he can't help but want the recognition he has desired since the flashbacks when he was a small child.
