If she fully understood her crimes, why did she want to be let out. Why didn’t she accept with resignation what she had done and live out her sentence without appealing for parole? It sounds like she was trying to have it both ways and God doesn’t allow that. One way or another. Either want out and believe she should be exempt from fulfilling her sentence or accept God’s grace, what she did, and then live out her life in prison without asking for anything other than being allowed to live her life after taking that of others.
I would guess human nature - there’s that desire to be free in all of us.
