Confession is good for the soul?

[Doorman]

Jake was dying.  His wife, Becky, was maintaining a candlelight vigil by
his side.  She held his fragile hand, tears running down her face.  Her praying roused him from his slumber.  He looked up and his pale lips began to move slightly, "My darling Becky," he whispered.  "Hush, my love," she said.  "Rest. Shhh, don't talk."
He was insistent.  "Becky," he said in his tired voice, "I have something
I must confess to you."
"There's nothing to confess," replied the weeping wife.  "Everything's all
right.  Go to sleep."  
"No, no, I must die in peace, Becky.  I slept with your sister, your best
friend, her best friend and your mother!".
 
"I know,"  Becky replied softly, "That's why I poisoned you."
