Could Eru change the very laws of nature if he wanted to?

That's getting a bit afield from the purpose of this thread, but if one examines "evil" in Tolkien's Arda as being defined "morally reprehensible", or "sinful", I would say no. Eru as Creator would also be the author of Morality, and thus "evil" would have to derive from a refusal to acknowledge and obey his authority.

By those standards though, I think Eru demonstrates his omnipotence in instances like I cited. The destruction of Númenor and the giving of immortality to Tuor were both unnatural acts, in that they would seemingly not have been accomplished without his direct intervention.
