I wouldn't have said anything, but I blame the mother more. If she felt stressed we are a great country to have social services. We even have free birth control! I understand post-partum depression, but I also don't believe in making excuses. If you did it, own up to it and get what you have coming. Murdering her kids took time. She could have called someone after what happened with the first one. I don't even understand why she wasn't charged for the murders of her 2 and 3 year olds. I feel the most sorry for the 7 year old.... he was the one old enough to understand what was going and that the mother he trusted was hurting him.
I feel terrible for him the most. I can't understand why the husband supported his wife through the whole thing. I have to wonder who supports the kids? Won't someone speak for what happened to them?
Oh a similar note... I found this article recently... a man was convicted of killing his 9 kids. He even had insest relationships with them.
