Life-in-prison inmates with no chance of parole actually live happy lives. Knowing they'll never get out of prison, they adapt. Their world becomes the prison, and they find their own meaning in it, without the stress and bother that comes with hope of getting out.
Death penalty inmates are quite the opposite. They have to eat and sleep their coming fate on a daily basis, and the mental anguish and fears that accompany it. It's a life of hell before death.
This is a dark day for past and future victims of Nebraska.
