Simply put.

Listen to Confessor Cromwell

If what he says is true people will die, but you will create life where it never existed before.

The needs of the many outweigh the needs of the few.

Megaton = 15 - 24 people? Blowing it up = trillions upon trillions of new universes.

Just for visual sake:

24

vs

1,000,000,000,000 (1 trillion)

Moral justification for the destruction of megaton.. you're welcome Capital Wasteland.

Moral justification for blowing up megaton?

"Moira brown lived there"

You're welcome. (???)

"This atomic mushroom cloud looks super cool, and fun."

Didn't work like you planned? Go back to the crater.

Yep, Bethesda got me good with that one. I should get an E for effort though.

It kills essential characters.

Hollywood dialogue aside, this philosophy is called Utilitarianism. It has been used to justify everything from war, imprisonment, capital punishment, the negation of animal rights and even the order in which patients are seen in an emergency room. Homeland Security in the United States is a good example of Utilitarianism. President Bush's justification for covert wire-tapping without legal warrant was that, by denying the personal liberties of some, he was better able to serve the greater good.

Utilitarianism would have us believe that whether an action is morally right or wrong depends entirely on its consequences ("the ends justify the means"). There is an obvious problem here: we rarely know the ends before we know the means. Rarely do we know all of the possible consequences of an action before we take an action. This, I believe, is what makes Utilitarianism a flawed moral system.

In the case of Megaton how do we know that "blowing it up = trillions upon trillions of new universes?" We do not. We are asked to accept the word of a religious fanatic who is also a hypocrite and possibly mentally ill. Given the absence of evidence I believe the proper moral decision is to spare Megaton.

However, because this is a roleplaying game my characters may take other actions. Character A may blow up Megaton and character B may spare it. It all depends on them.

try to justify yourself,NOWAY ...............YOUR ALL EVIL
