Wow DG, what a cheery topic!!

I have never experienced anything that puts me in a position to discuss the ins and outs of what drives a parent to murdering their child, so I think I'll leave that well alone.

I don't have children myself, but I can safely say that I've never felt like inflicting pain, let alone killing my recently acquired pet dog, regardless of how many shoes she destroys or wires she chews through!

I think it's worth pointing out the statistics for those who can't be bothered to read the full article;

The most recent crime statistics, for 2002/03, show that 99 people under the age of 16 were murdered in England and Wales, and seven in Scotland. More than half were killed by a parent, another 10 per cent by someone else they knew, and fewer than 20 per cent by a person unknown to them.

So we are talking about a very small number, so peoples tendency to "seek comfort in the belief that they are isolated incidents" would seem to be a reasonable reaction.
