These are not only for Fallout 3, but I practice them in any game ( but not real life XD )
Good Character:
I am the bane of evil.
Knowledge is my body and justice is my blood.
I have save over a thousand life.
Unaware of pain.
Nor aware of fear.
Withstood regret to kill many evil.
Waiting for real peace.
I have no regrets, this is the only path.
My whole life was Unlimited Life Saving.
Evil Character:
I am the All Evil Of World.
Darkness is my body and poison is my blood.
I have slaugther over a thousand life.
Unknown to guilty.
Nor known to love.
Have enjoy pain to torture many life.
Yet, those lowlifes are not enough for me.
So as I desire, Unlimited Life Suffering.
