Evil is not the opposite of good. Evil is to me the unnecessary expenditure of energy, mental, physical, or psychological. A Volcano can be seen as destructive, but it is actually creation in progress. Huge fires that sweep the plains are seen as destructive, but actually again are part of the life cycle of nature. Destruction is evil.
Destruction occurs in nature.
I disagree with this. Of course you are probably going to bring up the fact that Bambi was killed when the Volcano erupted. That would be assuming death is wrong. Still looking for one good example of the great Satan in nature.
