Confessor Cromwell

Confessor Cromwell is the leader of the Children of the Atom, a Megaton cult that worships an undetonated nuclear bomb left over from the Great War. He can be seen standing in the center of town, next to the bomb and praying to it in ankle-deep irradiated water. His name seems to be a reference to Oliver Cromwell and Edward the Confessor, both who where rulers of England at different points in history.

He is heard preaching to his audience about the teachings of the Children of the Atom.

Even if the player disarms the bomb in Megaton, Confessor Cromwell will not react to this and will talk to you as if nothing has happened. Also, since Cromwell spends all of his time in the radiation water, it will not take many hits to kill him. But it is odd since he doesn't die from radiation exposure.

He even beseeches Atom to "shape his fragile form" (or something - can't recall the exact quote), perhaps hinting at his knowledge of or even intentions to undergo a radiation-induced mutation.

Donating to the Church of the Atom through the dialogue options provided by Confessor Cromwell will give you good karma proportionate to the amount you donate.
