It would have been nice to get more Sasuke POV throughout the manga. Much of Sasuke's character development felt forced or inconsistent, and would be explained through vague or unsatisfactory means (Itachi / Uchiha massacre flashbacks, I'm looking at you!). The problem caused by all these rapid fire changes, coupled with the lack of POV, is that it's hard to get a sense of who Sasuke truly is. And of course, Sasuke is endlessly repressing many of his feelings / beliefs in order to live up to his current ideals or to focus on his current goals.
We get a lot of understanding about who Sasuke is in relation to Naruto; most often, Sasuke is the equal and opposite force. Both of them seek to grasp the "truth" of the ninja world, and come up with answers regarding how to solve the seemingly irreconcilable problems their society faces. However, the focus of the story is almost always on Naruto; it isn't until Naruto and Sasuke are finally able to come to an understanding that we are allowed to understand Sasuke. And, because this only happens in the final chapter of the series, that means that we only really get one chapter's worth of insight into Sasuke's perspective.
