If you want children, you should have a few. The world is not all bad and scary. There are nice, kind people everywhere.We just have to have better skills at recognizing them these days and more prepared to teach our children those skills as well.
Of course terrible things do happen to good people. But the risk is much lower of something bad happening to you , than the joy you will miss out on if you really want kids and don't have them
There are more good guys out there than bad.
This is a terrible, heartbreaking case. But let's remember there are more people in this country who would help a child, rather than hurt a child.
