*edit* In the fairy tale he wants the child only because he knows it's the most important thing the queen has. It's kind of a revenge thing. Also,there's an old superstition which says goblins used to snatch human bebês and change them for their own, which is where we get the word "changeling" used to describe a weird kid. I don't know what the goblins did with the kids they took. The superstition was used to warn people about leaving their bebês unattended.
