In my opinion, I don't believe that Dullindal is trying to make Shinn into a mindless "psychotic" follower, but rather that he's using Shinn as a poster boy. I mean, Shinn came from humble beginnings, lost his family to the previous war and through his anger rose through the military to become a "Super Ace" of ZAFT. I mean propoganda wise Shinn is the perfect solider: he's defeated countless enemy units, taken down fleets by himself, he destroyed the Destroy unit and then defeated the Legendary ace and pilot of the Freedom, Kira Yamato. Who better to be the poster boy of Dullindal's new campaign against LOGOS and those that would side with them? That is the reason Dullindal won't punish Shinn, and that is the reason why he is constantly rewarded. As for the comment that Shinn is insane, well...Taken into account what has happened to him during the course of the series, who would'nt be in a severely confused state after that? When you talk about the reason Athrun punched Shinn, being "upset that his best friend and girlfriend were blown up", thats pure hypocrisy. When you think that, then also think "but hey, didn't Kira kinda kill Shinn's entire family, and THEN kill the only girl Shinn ever loved?"...Think about it, cause If you think that Shinn deserved that punch from Athrun, then Kira should have gotten much worse then nearly dying.
