What about Gaara? The guy who helped attack Konoha, and murdered people for fun? He was made Kazekage, what about the Raikage who tried to Kidnap baby Hinata on the day of the peace treaty celebration? Or the Tsuchikage for using an S-Class Criminal Terrorists Organization for his benefit, etc?
Sasuke did more to help save the world than all of them, if he should be punished then so should they. But I see why you only mentioned Sasuke, because despite him committing far less crimes, he is far more relevant then they are.
More like he openly teamed up with the Alliance and fought against Obito, Madara, Kaguya, and saved the world from the Infinite Tsukoyomi. He's probably known as a War Hero.
