"When I was your age, my hands were already soaked in blood..."

"When a man learns to love, he must bear the risk of hatred."

— Madara Uchiha · Naruto

"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?"

— Pain · Naruto

"Foolish brother, if you wish to kill me - hate me, detest me, and survive in an unsightly way. Run... run and cling to life."

— Itachi Uchiha · Naruto

"Physical wounds will definitely bleed and may look painful but over time they heal by themselves and if you apply medicine they will heal faster. What's troublesome are wounds of the heart. Nothing is harder to heal. They're a bit different from physical injuries. You can't apply medicine for one thing and sometimes they never heal. There's only one cure for a wound of the heart. It's a bit bothersome and you can only receive it from someone else. What is it? Love."

— Yashamaru · Naruto

"The weaker you are the louder you bark."

— Tenten · Naruto
