"In the process of gaining happiness, one i certain to destroy the happiness of another" Ame Ochibana (Denpa-tekai no Kanajo)
"There's no such thing as a painless lesson, they just don't exist. Sacrifices are necessary. You can't gain anything without losing something first. Although if you can endure that pain and walk away from it, you'll find that you now have a heart strong enough to overcome any obstacle. Yeah... a heart made Fullmetal" Edward Elric (FMA)
"There’s no hope on the battlefield. It has nothing but unspeakable despair. Just a crime we call victory, paid for by the pain of the defeated. Yet humanity has never recognized this truth. And the reason for that is, in every era, a dazzling hero has blinded people with their legends and prevented them from seeing the evil of bloodshed. The true nature of humanity has not advanced a step beyond the Stone Age."
