why would it be so wrong to believe that a creator would use the biological laws of the world he'd created to achieve said end?
This is exactly the point I try to make with the more devout+less educated cross section of my friends when this topic comes up. I truly don't understand why they think God would try to play some cosmic joke (burying fake dinosaur skeletons in the earth, etc) on the unbelievers. It makes far more sense that God would simply use the system he created.
But the fact that there are no charges being pressed enrages me.
Are you a parent? There's absolutely NOTHING they could do to the guy that would be worse than losing a child. I wouldn't be surprised if he winds up comitting suicide intentionally, with the same gun. I can't imagine how much this guy's hurting right now.
I'd also betting his marriage is over. Yes, charges of child endangerment could be filed, but no punishment is going to change anything; no punishment that state can inflict will come close to what he's done to himself.
I am a parent and literally incapable of imagining the loss of my child. The thought is too painful for my mind to conjure. However, you should not assume that all parents care for their children. Look around and you will find plenty of examples of parents who could not care less about their kids. Regardless, remorse does not absolve either the step-father or the mother from responsibility for their negligent acts.
Today is the first day of the rest of your lossage.
