Minato hater?????????????????
Anyway, what is your definition of failure?
Where you expecting Minato to be carrying his students around during a war time in which he had some other dangerous missions in his hands?
Did I hear you say he failed at killing a kid? A guy that can vanish like he was never even there before? Last time I watched that fight, Tobi ran away for his life or where you expecting Minato to leave the village that was been destroyed and pursue Tobi?
MInato created and set the landmark for Naruto in a positive way...Unlike Itachi was created Evil Sasuke....
Minato is the saviour and doesnt have mistakes, his regrets are even invalid.
Itachi was a hero who made mistakes and later corrected them.
