Song lyrics Spare This Life by King Diamond

I, O'Brian of the Black Horsemen, forbid this sacrilege
You all know that this Demon Child has Abigail's spirit
Inside
But what you don't know is
That she is the reincarnation of my stillborn half-sister
Her spirit is not EVIL, nor is it GOOD
All it wants, is to make things right again
So spare this life, through which revenge can be mine
And Abigail can find her final peace
I, O'Brian, have spoken
Let it be done"
