What a bloodthirsty bunch!
I get that infanticide is unbelievably horrifying to imagine and perhaps even unforgiveable, but post-partem psychosis is VERY real and VERY serious. And I have to question if Andrea Yates was not also a victim here. From Wikipedia:
[Andrea Pia Yates] was suffering from a severe case of recurrent postpartum psychosis, after having had her last baby. She may have been suffering from additional mental illness for some years, since a pattern of such disorders is said to have run in her family.
Some believe or believed that her husband…was responsible for creating the conditions that culminated in the tragedy. Andrea's psychiatrist…testified that she urged the couple not to have more children, to prevent future psychotic depression, but the procreative plan taught by the Yates' spiritual mentor, Michael Peter Woroniecki, a doctrine to which Rusty Yates subscribed, insisted she should continue to have "as many children as nature allows".
Yates told her jail psychiatrist, "It was the seventh deadly sin. My children weren't righteous. They stumbled because I was evil. The way I was raising them they could never be saved. They were doomed to perish in the fires of hell." (This is consistent with Woroniecki's teachings, which are best characterized as "hellfire preaching.")
While I agree that this woman needs to pay for what she did...IMO, I think both the “spiritual mentor” and the husband should be bent over behind bars, ya know? She was coerced through religious brainwashing to have children she could neither care for nor protect-- not from her mental illness, and not from the harsh and emotionally abusive teachings of her church.
