Hmmm...

Vegans deny their child a proper diet out of a combination of ignorance and adherence to ideological dogma, causing the child's death, and they get thrown in jail for murder.

JWs deny their children a routine but critical blood transfusion out of a combination of ignorance and adherence to religous dogma, causing their children to die, and they face no criminal charges because they did it under orders from God.

Seems fair to me.
