The woman is lucky she had so long to sit in jail before being executed that she was able to find Christ and change her life. It shows God’s mercy and grace that she had this time. Also time to help others in jail before her sentence was carried out.
But she had temporal consequences to deal with that she still had to answer for. Would I have minded that such a person, changed this way, would have received a stay of execution from the governor and remained in jail the rest of their lives? Maybe not, given her change and desire to help others. But I do not think it was an outrage or a disgrace her sentence was carried out.
A small part of her debt is to the state and the law gives the state the power to lessen her sentence but the real debt of justice was to the victims and the victims’ families.
Really this woman had only one path to justice and that was through her death.
I think it was a Clint Eastwood movie in which the character says something to the effect that murder is the worst crime, you take every thing a man has and everything he is ever going to have. There is only one way to pay off a debt like that.
