Take the slut and kill her period. I don't care if she had ADD, PMS, Post partum depression, lost money at the casino, there is no excuse and no fucking use for people like this in society. And if this person was my own relative even my Grandmother i would want the bitch dead period!!
And who cares about motive, she killed her kids one by one then called the cops, gimme a break. And I think any lawyer or doctor who gets up and says with a straight face that she is some 'victim of circumstance" or whatever should be hung by the nuts as well.
I feel bad for the father because no matter what happens in this situation he is the one that is ulimately fucked, not her, us or anyone else except him.
