Morality stems from harm. It's wrong to harm someone. As human society has evolved, this principle has been applied to society as a whole. It's wrong to do something that harms society, and the individual who did so must be punished. And from this you derive all the morality of the world.
Someone mentioned honour killings, and they're a perfect example of this. Someone has shamed family/society/whatever, so they must be punished.
It's only the punishment for harming individuals or society that distinguishes one morality from another.
