From quotes that I have readily available, I have a few...
"You seem to take delight in seeing other people suffer. And you treat life like a disposable commodity! You destroy homes. You take the lives of innocent, peace-loving people. You even take the lives of children. Well, now it's your turn! I'm going to finish you! How many people begged for their lives before you killed them? Did you show mercy when I asked you to spare my best friend Kuririn?! What I represent can never be destroyed!"
- Goku, Dragon Ball Z
"I'm not a proper doctor. It's a really complicated case. Your chance of survival is very slim, but I can save you. If you don't want to believe in me, that's fine. But if you believe in me, come see me any time. I'll help you under one condition: you can never complain about what I do. The journey is just beginning. Don't give up! I'm trying to make the impossible, possible!"
- Black Jack
"If you want water, dig for it yourself! If you want food, then plow a field and plant it! But you're a hyena who won't do that, and instead steals from others! Today, you lost the right to live!"
- Kenshiro, Fist of the North Star
"When you're in a town like this all covered with smoke, you forget that there's a world outside. Nothing amazing happens here. And you get used to that, used to a world where everything is ordinary. Every day we spend here is like a whole lifetime of dying slowly. But now Haruko is here. That's how I know there really is a world outside."
- Naota (Fooly Cooly)
"I wonder, how much effort does it take to make a person happy? Unhappiness, I believe, is like a spiraling series of events. Once you get into it, it's very difficult to get out. To escape its grasp truly takes one's best efforts, to the point where people think you've gone too far. Yet, eventually, you are able to take control. Isn't that happiness? Rena believes so. But even so, I don't plan to be spoiled, expecting everyone to accept my reasoning, I guess... Then, shall we begin? Ryuuguu Rena's first and final story of the endeavor of a lifetime!"
- Rena (Higurashi no Naku Koro ni)
"If we all reacted the same way, we'd be predictable, and there's always more than one way to view a situation. What's true for the group is also true for the individual. It's simple: Overspecialize, and you breed in weakness. It's slow death."
- Motoko (Ghost in the Shell)
"Gentlemen, I like war. I truly love each and every kind of war man can wage on this planet. But for those of us who have had to endure a half a century among these dark depths, just any war will not do! I want a war waged like hell itself! Let's drive out those who have forgotten us, let us awaken those who have fallen into a deep sleep. With an army of 1000 vampires, we will burn the world to the ground."
- The Major, Hellsing
"How vigorous, I like it! I wouldn't have it any other way! I wouldn't have you any other way, Battler! Try to deny me, I'll completely and thoroughly smash you into bits! Let me make you surrender over and over again. I'll teach you, one who has licked my shoes, the taste of defeat over and over again!"
- Beatrice, Umineko no Naku Koro ni
"The same goes for you. There is no sanity here. Our end will be the same, even if we accomplish our goals. You will destroy it while I will protect it. But there is nothing to be gained, no matter whose goal is achieved. You came here knowing that. This is a meaningless battle. We are two madmen engaging in useless folly."
- Kotomine Kirie
