Her first error was murdering her husband. Perhaps you can find enough sympathy to bring her innocent husband back from the grave. I am willing to go way out on a limb and say that he would appreciate that.
I have not said she is innocent and doesn’t deserve a severe punishment. I do not think she should receive a punishment even more severe than the actual killer. She has shown considerable contrition, asked for forgiveness, admitted her guilt, and most importantly brought the Lord into her life. I cannot ignore that. I wish we would execute folks such as Manson, Hassan, the Boston bomber, the 911 terrorists, the Colorado shooter instead of this person.
