I empathize with your concern about the death penalty in this case. But I can’t agree with some of the reasons that you might oppose its use here. The fact that she was a mother is tragic, but should it mean that no mother should ever face the death penalty? Remorse is commendable, I suppose, however I don’t think that after the fact actions can erase what was done or the intent at the time. And of course remorse makes perfect sense— when you get caught. I am happy that she appears to have come to have faith in God, and to partake of the Amazing Grace Christ provides, even to killers and other sinners (such as I).
As for plea bargains, I know that they are necessary in order to keep the criminal justice system going, but in cases of capital murder, I am not sure justice is best served by such deals.
Also, as someone who actually supports the death penalty, I am concerned that executions such as this could erode public support for the death penalty.
