In her favor, she is probably the one member of the group that has accepted responsibility for her role in the killings and made efforts to make something of her life. I hope those efforts are sincere.
However, given the cruelty of her crimes and out of respect for the family members of the victims, I think justice requires that her efforts to redeem her life continue to be conducted from the inside of a prison.
One who has done that is David "Son of Sam" Berkowitz
Good post she just might need to live her life out in prison for what she did.
