There life was on the line (Madara and Sasuke), the most dangerous characters in Naruto, imo they should've died during the war, i mean there hyped died awhile ago and tsunade no longer is hokage, she didn't have kids, neither did mei, kishimoto fcked up gaara's head and the rest of them are just old and unproductive, it would've been wayyy better, if they died during the madara fight or Sasuke had a fight with them before he fought Naruto
