"evil" as we think of it, is just a creation of our minds. Evil is a human invention, that is only done by humans. There is no thing as "evil" and "good" in nature. Nature jsut strives to survive. We may interpret things as good or bad, but thtas just so we can understand it in our way.

Now, there are somethings that are harmful, or out of the norm. Humans sterilizing land for the sake of just ourselves, rather then nature as a whole is harmful, and most people would say its "wrong". If there IS anything actualy wrong in the whole picture (not jsut in our terms), is that most of our activities upset the balance of nature, and we CHOOSE to cause harm, when there is another alternative.

Good and evil is just a concept so we can better understand out capabilities as a species, not really something in nature ( im aware we are part of nature). So does it really exsist? ID have to say generaly no.
