Quite interesting responses, the majority coming in with the sympathy vote.
What if he had been cleaning his shotgun and it had accidentally gone off, killing his child. Or he was playing with her with a large sword and accidentally stabbed her through the heart? Still no price to pay for accidentally taking a human life? - Where is the responsibilty? I am sorry but if you commit such a crime, even if it not pre-meditated, extenuating circumstances can be taken into consideration but there must be some price to pay, otherwise you could take a life and always claim it was accidental in order to escape the consequences. If he was before me, then I would state that if you take a life, then you must sacrifice yours, albeit translated into a prison term, except in cases of self-defence. I am sure person is full of people racked with guilt, but people must take responsibility for their actions and face the consequences when necessary. If indeed, this story is true, can you even imagine being cooked alive? Sorry, but he must face the consequences.

If you're living life on the edge, you've got too much room.
