OK let me change this up a little bit.  Let's say I married an alcholic women and we had a kid together. One afternoon after picking up our daughter from school, she decides to stop at a local bar.  She cracks the window just enough, in her own deluded mind, for the girl to get some air.  She tells herself that she is only going to have one drink and she will be out soon.  One drink turns in to six or seven.  When she comes out,  our daughter has succumbed to heat exhaustion.  Horrified, she dials 911 before fainting.  Whe the cops arrives they have revive this woman who starts screaming how this was not suppose to happen.  
At the trial, instead of someone laughing that they only got twenty years, we have a woman crying and saying how sorry she is, and that she never meant to do this to her baby girl.  What is my reaction then?  Honestly, I don't know.  I couldn't tell you until I was in that situation.  I'd imagine I would feel immense guilt and blame myself for leaving my daughter in the possesion of this alcoholic.  Cursing myself that I did not get divorse and custody of my child.  I would hope that I would not be calling for blood, but like I said I don't know.
