Mystic Muse reads The Silmarillion.

I'm not sure that extremely powerful godlike beings could be classified as children.

Eru could have stopped Melkor from doing anything, but that evil came about because of free-will. Remove the free-will and you remove the evil, except lack of free-will, being little more than a puppet of a creator, isn't an improvement.

Thats all getting a bit philosophical though, which is probably more than we need to get into.
