Sorry but Sasuke and Ay
Sasuke: 1.) Tells Naruto to get stronger then him and when he does he gets pissed of then leaves the village.
2.) Doesn't kill naruto at the valley of end because he didn't want to get strong the same way as Itachi, then when
He see's him again after 2 1/2 years the first thing he tries to do is kill him.
Ay: 1.) lets the fear of his brother dying control him for an entire arc then threatens to kill Bee himself after telling
Naruto and Bee not to let their Emotions cloud their judgement ( which he did for the entire Gokage Summit)
