what would of happen if all of the team 7 when rogue

So not possible. First of all, Naruto's dad is the freakin Hokage. And he plans to follow in his pop's footsteps, so... Also, Sakura is too soft to go rogue. But if they did go rogue somehow, Kakashi would have a heart attack and die!

If team 7 will to be a rogue ninja, they might do something dangerous and would make the ninja world chaos and might also free Kaguya and the world might ended.
