I mean let me put this into perspective.
5 years is the minimum, obviously, and much too kind.
10 years is about right for therapy, cooldown time, and just a little bit of "btw you fucked up and are in jail now". That's what I would recommend.
15, 20, even 25 years are all justifiable, on the basis of letting the poor kid grow up (and live a little) without the danger of interacting with her psycho mom again during her development. An extended period with a 25-year minimum parole even, fine! We expect the mother not to do anything that would get her parole denied, and if she does, well, there it goes.
That's the max, though, the absolute max you can justify. We don't have to protect this kid until she's thirty-fucking-goddam-two, or if we do, then it's not going to help to wait until she has vulnerable children of her own. Gfj on that one.
99. It's a thoughtless number, the kind of number you see in banks when someone is TOTALLY NOT DOING ANYTHING SHADY NO SIR. Fuck that.
What I'm pissed off about isn't primarily the all-encompassing spitefulness of the outcome - that certainly isn't going to make me any more forgiving though - it's that you've managed to take a psychopath who committed a felony worth 10-25 years against a toddler and made her the victim. Not just a victim, but an outright martyr, if the defense has anything to say about it.
G. F. Fucking. J. You worthless pieces of shit.
