??? Tell me you never forgot that his first dream was to become Hokage. That is his primary goal. Always has been.
His second goal was to bring his friend back from the dark side.
Also, if Naruto thinks Konoha or the world is in danger then he would strive to protect it and place that above the two I just mentioned. He is very much a moralist. He's simply using Sasuke as an instigator to inspire him to become better.
