Heya Mmario...I'm a day late and a dollar short, as per usual. ;D

You mentioned: "I just cannot - (and I speak from a pretty knowledgeable experience of depression) imagine a depression deep enough to allow a mother to not know killing her children would be wrong".

Well, there's depression and then there's depression. A family member of mine is a bi-polar sufferer. And while it *used* to be called "manic-depression" the crashes this poor soul has had to endure come about as close to the kinds of depression I myself have witnessed or suffered like pterodactyls resemble mosquitoes. He once drove off into another state, banged on the door of a total strangers house, and yelled at the rightful owners to get out of his home. Chemical imbalances like this and severe post partum "depression" should not be termed as they are. It is not depression in it's usual state. Even severe "clinical" depression has little to do with it. It's psychosis.
