Naruto's and Sasuke are dumb

[HENI]

It's not like Sasuke to try and kill someone twice.

He tried to kill Madara twice

naruto knowingly let orochimaru live so boruto and the next generation need a new villain / Punching bag so they can surpass their parents.

Kishimoto didn't even bother having somebody at least hint who created them though.
