Nope,this guy's existance makes the manga predictable.
Sasuke's existence is what keeps the manga from being a generic underdog saves the day from the bad guys shonen manga.
As long as this character is alive what is there to except from this manga?
Oh wait,that hyped final fight between him and Nardo.
Therefore my point stands,this guy makes the manga predictable.
take him out = less crying about the past for one and takes away stuipped sht that didn't really even matter to the story yea so your brother killed your clan whopped freaking do get over it.
