In KH2 FM, Xemnas called Aqua's armor "friend". Later, Xigbar told Zexion that he was listening to Xemnas talk in the Room of Sleep, and that he heard another voice. It's possible that it could've been Aqua's. I believe that Xemnas was seeking assistance from her to help him succeed in obtaining Kingdom Hearts, which was his evil plan. So obviously, Aqau helping him would possible make her evil too.
