Thanks for this answer.
TRIGGER WARNING: INFANT MORTALITY
You insist that these deaths happen through neglect. As you say, neglect can be purposeful or it can occur through recklessness or carelessness. None of those apply to these cases, however, because your starting point is that active thoughtfulness can prevent all of these types of neglect. The point is that active thoughtfulness when around children is never 100% for all children or all adults at all times. Not because the parents can’t be bothered. Not because they don’t care. Not because they prioritize work. But because of the way our brains function. Nobody can be 100% actively thoughtful about all things at all time. Do you never do two things at the same time? Are you actively thoughtful when you’re ironing and listening to the radio at the same time? Which activity are you actively thinking about? Do you never chat on the phone while you’re watering the plants? Which thing are you thinking about? Have you never cut your finger while cooking? Why weren’t you actively thoughtful not to do so?
TW: there is significant research showing that the risk of death by SIDS can be significantly reduced by co-sleeping and ensuring a baby sleeps on its back. This is a parenting forum and I hate doing this - so I hope my warnings are enough. So, for every parent - mother and father - who loses a baby to SIDS when not cosleeping and not ensuring the baby sleeps on its back: were they neglectful? Arguably, more thought goes into deciding not to cosleep and not staying awake watching your baby all night than goes into the daily routine of home -> drop off -> work -> pick up -> home each and every day.
So, when you say every unnatural death caused by another (sorry I’m on my phone and can’t see up enough to quote you correctly, pls insert your own phrase) should have consequences: what do you suggest for bereaved parents of Sudden Infant Death Syndrome? A criminal conviction? Jail time?
There is no absolute morality about this. Hundred of millions of children have died around the world without a single consequence suffered by their murderers (eg in war, assisted famine, abuse etc). There SHOULD be consequences but there are none. And as a species we accept this because we haven’t ever prevented it. All to say, there’s no absolute to this.
But, fundamentally, the point is that these deaths don’t occur through neglect. They occur through non-100% active thoughtfulness. And, if you’re actively thinking about your own child then you’re not actively thinking about the child running into the road in front of your car who you run over and kill. Is that ok with you, to suffer criminal consequences for that? This is any of us, at any time, in all regards. Sometimes the consequences are immaterial. Sometimes they’re tragic. The “offence” is the same. Criminal consequences would have no rehabilitative or corrective or preventative effect. They would only serve to punish. That’s biblical justice, an eye for an eye. We’re better than that.
