@nobleme01 Kakashi saw Pain look at the ground, pick up a nail, stretch his fingers and throw it calmly; Sasuke was smiling at Naruto, distracted and almost defeated after a difficult fight, the Sharingan couldn't even be activated in that situation.
@EMK_Freesmoke They wouldn't be that strong; after all, they don't seem like good sensei. But Madara would teach them Uchiha secrets, like Izanami, and Sasuke would use it in battle to kill Naruto.
