Are we forgetting that she had THREE other children who were taken from her by the state?
Things have to be seriously neglectful before the state can act. So, she ruined 3 previous lives and killed this one needlessly, so at least the sentence she received will act as a preventive for her having the opportunity to ruin/murder any more innocents.
Instead of painting her as the poor victim here, how about considering the REAL victims who did nothing to deserve the treatment they received at her hands?
She did not have to leave an infant to die a slow agonizing death. There were many options available to her (including birth control to assure not getting pregnant AGAIN)
If nothing else, jail will prevent her from damaging/murdering future lives. It’s pretty obvious she lacks the ability to learn from her mistakes so depriving her of the opportunity to keep making the same mistakes is perhaps the best, if imperfect solution, to this situation.
It’s not ideal, but at least it takes her off the playing field.
