Sasuke definitely became a villain in my eyes when he left Konoha at the end of Part I. He still had honorable traits about him though, such as not wanting to mercilessly kill anyone who wasn't Itachi. However, he was willing to kill people who got in his way of revenge, including his former comrades. After he learned the truth about Itachi, is when in my view, Sasuke "truly" became evil. In the beginning, Sasuke still cared about his comrades in team Taka when they were fighting against Bee, but disregarded both Suigetsu and Jugo in his quest for revenge against Danzo. Even Karin became troubled with how evil he had become, with his chakra becoming cold. After that, he became a killing machine, killing countless samurai, sacrificing Karin for revenge, wanting to kill everyone in Konoha, wanting to kill anyone who disagreed with him, and their loved ones. He was truly evil, and perhaps even crossed the Moral Event Horizon.

He really started to back away from these ideals after he met a reanimated Itachi.. and that's when both he and the reader became confused about what his true ideals are now. We know he wants to become Hokage, and that he wants to protect the village now, though it's still unclear what kind of Hokage he wants to be. He puts the mission first, but will come to someone's aid as long as it does not interfere with the success of the mission. That's where I think Sasuke is now at this point.
