Yes, I think the proper punishment for her crimes (all of them, murder, character assassination, countless lies, dog kicking...) is for her to live to a ripe old age, in a cell, with little more than her own thoughts and memories to keep her company. Some sense of sanity and truth will eventually invade her dogmatic, obstinate denials and will drive her to a level of insanity she never fathomed existed, much less become a part of her every waking and dreaming moment.
I abhor violence or even intentionally hurting anyone's feelings, but for the simple fact that she still refuses to tell the truth of what she did to Travis, in the face of all of the evidence, she deserves this punishment, not to be relented or lightened until she has come clean, wholly and with no reservations or equivocations.
I could never forgive her actions, but she *might* merit a modicum of sympathy if she would only be honest. I believe this to be beyond her, as our definition of honesty is a foreign concept to her.
So she shall be caged, to age, and think, and remember, and suffer. She could have changed her fate, even as late as this past January, but she defiantly chose not to. To each their own.
