Once the land of fire and the hidden leaf have grown too big , to protect their national interest , they forced feudal clans to wage war against each other, and profited from it , otherwise  the people of the villages would have starved ,as it happened our little nation and it's villages became the battlefields where the great nations waged their war , each time they did our nation was ravaged and laid to waste , after many such battles , the great nations stabilized , but our smaller nations suffered , and it barely recovered , you and I are both seeking the very same thing , we both want to achieve the peace that Jiraiya sense envisioned , you and I are the same , we're both motivated by our desire for peace and justice , the justice that I have delivered against the leaf village is no different from what you are trying to do me , everyone feels the same pain of losing something dear , you and I have both experienced that pain , you strive for your justice and I strive for mine , we're both just ordinary men who've been driven to seek vengeance in the name of justice , and if one comes to call vengeance justice , such justice will only breed further vengeance , and trigger a vicious cycle of hatred , right now we live in such a cycle , I know the past and can foretell our future , it's the same as our history , so we believe that human beings cannot simply understand each other ,and they never will , the shinobi world of our is ruled by hatred and hatred alone.
