Pathos of the Shinobi

The one thing that couldn't hide in the world of Shinobi was ill-intent. Evil. Sin. It was rampant throughout the Elemental Nations and infested every village to it's core. That's why the Child was needed. He could sense the true heart of man, and he would know the truth that the Kyuubi no Kitsune would profess- That the world of Shinobi was rotten. That it was time for an end.
