"Even innocent foolish children will grow up in the face of pain, until their thoughts and beliefs are the same as their doubts"
"Love breeds sacrifice... which in turn breeds hatred. Then you can know pain"
"Just by living, people hurt others without even realizing it. So long as humanity exists, hate will also exist. There is no peace in this cursed world. War is just a crime paid for by the pain of the defeated..."
"Sometimes you must hurt in order to know, fall in order to grow, lose in order to gain because life's greatest lessons are learned through pain"
"Love is the reason why there is pain. When we lose someone precious to us, hate is born. Vengeance is the product of that hate and so death follows. But in death there is only more death. This will give rise to more pains. In this cursed world we live in, it is a cycle of hatred that will not cease. You and I seek the same thing that Jiraiya-sensei wanted. Let me ask you this: How will you confront this hatred in order to create peace? "
"We are but men, drawn to act in the name of revenge that we deem to be justice. But... if there is justice in revenge then that same justice will breed only more revenge... and trigger a cycle of hatred"
"Religion, ideology, resources, land, spite, love or just because. No matter how pathetic the reason, it's enough to start a war."
