Yeah there is lot of way to prevent Sasuke from defecting the village, almost killed leaf ninja genin and chuunin Shikamaru(except the older chuunin who died), leaving his teammates to die, almost killed karin, and become infamous criminal group who madara sorry Obito who went in on killing off the rest of the Uchiha clan.



No even bother with fact that Sasuke was mentally scared who should been in a therapist, I mean he been anti-social on his whole until he become a genin (if you count it as socializing). Itachi is kind of a idiot when he should know that what he did to Sasuke who would become a insane until it wear off later. I never understood on why or how Naruto and Sasuke are best friend when they are at each other throats.



I think rest are too forgiving on Sasuke lately when he should have get an ass kicking for being a moron. Like how Karin forgive easily Sasuke for almost killing her if I was her I would tell Sasuke to go screw himself.



Sorry for rambling on, and they are not even that strong in Naruto world when no one even bother to get creative with their powers like how one guy from Raikage who stand toe to toe against a 8 tailed bijuu, Lee weight lift, tsunade strength, seal method, and Naruto shadow clones transfer knowledge to original when Naruto should have took advantage of it to improve his other skills (hand to hand combat, weapon training, seals, etc..).



One Piece Is straight up over kill even two year time skip the strawhats are freaking strong Zoro goes toe to toe with his strength against a freaking Dragon (Punk Hazard), Luffy vs Hody Fight, Nico Robin can make giant limbs, Chopper can control is monster point.
