He'd still be the same.
Itachi, on the other hand, would be insanely powerful.
^ yess...
Same for every other ninja.
He's had an intent to kill before, like vs pain (not after the fight when he talked to nagato).
But it makes him seem weaker imo.
Naruto with killer's intent is a nightmare, he is literally a one man army, and between sage mode, and his reading of emotions, no one could stop him.
minato and kushina created a monstor
Evil naruto is honestly something I hope we get a glimpse of before Kishi finishes the series, I'd love to see how naruto acts as an antagonist temporarily, just so everyone can know how merciful he is when he's not trying to shove a TBB down your throat.
