Their own village's great ship was already on the verge of sinking.
There was no reason to drag the entire village, with its millions of people, down with it. Tsunade had never been a cold and ruthless person. She could be endlessly cruel to outsiders, but when it came to her own people, she could never bring herself to be heartless. Those willing to live and die with Konoha could stay; those who wanted to seek another way out, Tsunade was willing to let go as well. This was the last bit of mercy she could show the villagers in her capacity as Hokage.
In this respect,
Tsunade could be said to be quite similar to the First.
And precisely because of this,
in the vast Land of Fire,
apart from Konohagakure,
not a single Ninja could be seen anywhere.
Naruto wasn't surprised by this sight. Even the wandering Ninja who might otherwise be roaming around and causing trouble were, at most, taking advantage of the situation in remote areas. In the heartlands—including the Land of Lightning and Land of Water, which had already been completely pacified, as well as the Land of Hot Water, which had been brought under their rule—these wandering Ninja had vanished without a trace. Or rather, every one of them who dared to cause trouble had been mercilessly slaughtered by the Snow Ninja Naruto had ordered into action!
The newly established order of the Shinobi World
had no place for these lawless troublemakers!
Anyone who might threaten the establishment of the new order or disrupt social stability and harmony—
in Naruto's dictionary,
there was only one word for them:
"Kill!"
Naruto especially loathed those who had tried to profit from the Shinobi World War. Once confirmed and captured, the best outcome awaiting them was death.
