Wow, you're being biased. Leaving out Sasuke's side? I'll show you the full truth. Corrected.
Gaara:
>Felt alone
>Wanted acceptance
>Can't feel physical pain cuz sand shields him(straight from his mothers coochie)
>Mom's brother let him feel he is not alone
>Mom's brother tried to kill him
>He kills mom's brother unknowingly
>Mom's brother tell him he's a monster before dying
>Loses it
>Need a purpose
>Alone and hated
>Called a monster
>Finds answer: Lives to kill Kills people that had nothing to do with him, at all. People who didn't even know he was jinchuriki.
>Becomes a weapon for his village
>Later found he was not alone
>Put in work(like a baws)
>Became accepted
>Became Kazekage
>Became a hero
And note that the only time he never did something unacceptable and him being "forgiven" was simply the peace treaty between both villages because Orochimaru was the one pulling the strings by killing their Kazekage and acting as him.
Sasuke:
>Brother kills clan
>Forces Sasuke to watch it for 72 hours in tsukyomi world, twice.
>Becomes a missing nin(kaput 1)
>Joins the man who killed a kazekage, hokage, konoha and is a missing nin himself(kaput 2)
>Lives for revenge Due to the fact his whole family was wiped out.
>Defeats 5 s-rank criminals; Deidara, Orochimaru (Though he brought him back), Itachi, helped defeat Kabuto, and killed white zetsu
>Kills his brother A missing ninja that was wanted by Konoha for the genocide of their strongest clan.
>Finds he was ordered
>Joins a criminal organization(kaput 3)
>Tries to capture a jinchuriki and gets spotted, sets off what could trigger a war between konoha and kumo(kaput 4) Gaara was going to kill anyone he could in the chunin exams. If he could kill HIruzen, he would've. That could start a war too.
>Kage summit happens as a counter measure to akatsuki
>Shows up, kills many samurai and the hokage, takes an arm of the raikage, refuse an offer from Gaara pleading it's not too late yet, says his only goal is in darkness and gets labeled an international criminal(kaput 5) To be fair, yes. That's bad. But let's be honest here, Raikage was trying to kill Sasuke because he thought Sasuke killed his brother. Sasuke tried to kill Danzo because he ordered his brother to destroy his whole family. HM?
>Tries to kill his teammates(kaput 6) Gaara has threatened to kill his teammates a lot.
Also, Sasuke vs Naruto, yes Sasuke tried to kill him.
When Sasuke was first shown in shippuden, Team Yamato was trying to capture and kidnap him to go back to a place he didn't want to be. You honestly think Sasuke wouldn't fight back?
And don't get me started on when he tried to kill Sakura. She tried to kill him too, so did Kakashi. The only one who didn't try to kill him was Naruto.
>His same organization starts a world war where the leader of the group wants world domination(kaput 7) Yeah, he also saved it by:
1. Helping defeat Kabuto and stop edo tensei; which, btw, Ohnoki said, "Whoever stopped edo tensei is a hero!" So he and Itachi are heroes.
2. Came with The four edo kages to save the alliance's ass. He and Oro are heroes here.
>Comes to warfield claiming to be on their side, says he gonna become hokage.(I thought I was reading a parody Lol, me too a bit. XD)
So is Sasuke like Gaara? Yes.
Amaterasuice, out.
