The real tragedy here is that help and support just isn't available for so many families in this position. Not from the state, not from communities, not even from extended family in many cases, and people can become completely desperate and just snap. And then, inevitably, extended families, friends and neighbours are "shocked", "horrified", "outraged" that something like this could happen... but you can bet your life than when he was alive and when she was probably quite obviously in need of help, none of them wanted anything to do with "the weird kid" who was "a lot of work".
