They should still be held accountable for their behaviour though.
Here's some examples of other cases where men claimed they had mental health issues resulting in them killing their kids or families. These popped up on a Facebook post for me but I've checked the source and found newspaper articles for them all.
Benjamin Cole, Oklahoma. He killed his 9-month-old daughter. He had a paranoid-schizophrenic diagnosis and was found to have a growing brain lesion. He was guilty and Oklahoma executed him in October 2022.
Reginald Brooks, Ohio. Days after his wife filed for divorce, he killed his three sons: 17, 15, and 11. He then left town. He had paranoid schizophrenia too. The court that sentenced him even said he was mentally ill before, during, and after the killings. Ohio executed him.
Richard Fairchild, Oklahoma. He killed his 3-year-old son. He had schizophrenia-spectrum, psychosis, delusions, and brain damage. He was executed in November 2022.
André Thomas, Texas. In 2004, in the middle of religious delusions, he killed his wife, their 4-year-old son, and 13-month-old daughter. He said God told him to do it. He has a long schizophrenia history, including hearing voices as a child. A jury heard the insanity defense and rejected it. He was sentenced to death.
Larry Robison, Texas. Diagnosed with paranoid schizophrenia. He killed five people, including an 11-year-old boy. He ran an insanity defense. Texas executed him.
While I don't agree with the death penalty for anyone, it's a marked difference in how these men were treated for their crimes and the court case fiasco of LC. I would be shocked if there were legions of men out on the street protesting about their incarceration or saying 'same here'. I'm equally shocked that women are doing it.
Whilst I sympathise with anyone suffering PPP ( but I'm not convinced LC had it), it does not excuse her actions. There has already been some copycat crimes in the US with a least one woman I read about killing her son and claiming he was the antichrist.
