She still needs to rot in prison.
Then she needs to rot in hell.
She's rotting from the inside out. She and her husband have amassed millions and have gotten away with more crimes than just about anyone alive. She still commands an army of loving, dedicated sycophants who would die for her. All told, she has the wherewithal to request and enjoy the fruits of every mortal pleasure. Yet deep within the recesses of her being, she is empty.
Would you want to be her?
A prison cell would be justice served, but she's already in prison.
Then, there is the moment after she takes her last breath, and she finds herself standing before the Judgement Seat.
