^ The kages attacked him one by one and took turns at that, for no reason. It was Konoha's matter, they never should have interfeared when Sasuke didn't even want to fight them. And the way you are hand-picking Sasuke as the ONLY person whose wrongs can never be justified is nonsense. If Gaara, who killed people just to feel alive can be called 'angelic' Sasuke has literally done nothing to even compare to this or any other kage atrocities. There is no way to justify anyone's wrongs. One nations hero murdered countless others. Again, who would forgive whom? Keep believing whatever you want. Your views on Justice and 'to justify wrongs' are odd and unflattering.
1. When has Gaara killed anyone in Shippuden?
2. Sasuke attack Gaara first -

3. What has Tsunade done wrong?
4. How can you justify that Gaara (being that Naruto and Sakura aided Gaara in saving his life) interfering gives Sasuke reason to strike the leader of Sand?
5. He killed (or was going to kill the temporary Hokage), He fought the Raikage, He tried to kill both Sakura and Kakashi, He nearly killed Karin, Would have killed Sai, Naruto, Sakura and Yamato (or attempted too) if it weren't for Oro, He's made it his sole mission to betray and destroy the leaf, he's joined Akatsuki, he's tried to capture Bee and lead him to his death, he partnered up with another known criminal who tried destroy the leaf
Provide me a manga fact where Gaara has done crime(s) equal to or greater than the ones Sasuke has committed
...oh wait
And there's nothing with my views on justice if you're a criminal you get punished, depending on the severity of your crime, a punishment should fit to that degree
