People cannot win against their loneliness because loneliness is this world’s worst kind of pain.

Kabuto: It's always easier said than done. I just said that this jutsu had no weaknesses or risk... Itachi: Every jutsu has its weakness. This jutsu's weakness and risk is...the existence of me!

I've told you before. You shouldn't judge people based on appearances and your preconceptions.

Darkness... When everything that you know and love is taken from you so harshly, all you can think about is anger, hatred, and even revenge. And no one can save you.

We don't know what kind of people we truly are until the moment before our deaths. As death comes to embrace you, you will realize what you are. That's what death is, don't you think?

I never go back on my word! That's my nindo, my ninja way!

The weaker you are the louder you bark. -Tenten
