No. This better compares to giving a 5 year-old the keys to the car, showing him how to start and shift it and where the pedals are, turning away, and letting him run over his sister. It's like handing a bottle of sleeping pills to a kid, showing him how to eat as many as possible and wash them down with water, turning your back, and letting him give the whole bottle to his sister. This is not a "tragedy". Those examples you give are tragic, but this is different. These parents are criminally negligent- but maybe not in Kentucky.
