You are only able to make that assessment based on 20/20 hindsight. What real evidence do you know he had available to him before she murdered her children that she was emotionally unstable?
From all the information available the husband had been told by psychiatrists in no uncertain terms that his wife should not have any more children due to repeated psychotic episodes after childbirth. She walked around like zombie and showed signs of severe depression even when she wasn't psychotic. If that doesn't show that she was emotionally unstable, I don't know what would.
I do not always blame the husband; however, it certainly seems appropriate in this case.
Sure they did. The same shrinks that recommended she needed to be hospitalized because of her condition. Oh wait, they didn't recommend that.

All this anger towards the husband and none toward the treating physicians or shrinks?
They say Yates planned to drown the children when she was alone with them, after her husband went to work and before her mother-in-law arrived. Then Yates called 911 and later told a detective she killed them because she was a bad mother and wanted to be punished, according to witnesses.
You are willing to blame the husband for the wives actions. Why do you also not blame the mother-in-law?
