Greed may not be good, but it’s not so bad either. You humans think greed is just for money or power, but everyone wants something they can’t have.

Teachings that do not speak of pain have no meaning...because humankind cannot gain anything without first giving something in return.

I want you by my side. Forever. (Full Metal Alchemist)

Do you wanna play? Everyone's dead, so I got bored. Did you come to play with me? --Wrath

There are many questions in this world that have no answers.

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.

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?
