So that the new generation that will be born can enjoy happiness. To pay the cost we will have to shoulder corpses and cross a river of blood (Riza Hawkeye -- Fullmetal Alchemist)

Humankind cannot gain something without first giving something in return. To obtain, something of equal value must be lost. This is Alchemy's First Law of Equivalent Exchange. In those days, we really believed that to be the world's one, and only, truth.

I'M NOT SHORT!!!!! ~Edward Elric

All right people, listen up! If you've got a family back home waiting for you or if you just want to save your own skin, turn around and walk away. Also, women! I have no intention of fighting any women!

You cant gain something, without giving something in return

You've certainly mellowed out... you used to be fun, full of life and emotion. Lust, Greed, Sloth, Gluttony, Envy, Wrath, and Pride. Of course, excessive want will destroy anyone, but those same desires are necessary to understand what it means to be human. Why did you rid yourself of them?
