What does the word "good" mean to you? For that matter, what does the word "evil" mean to you?
The way I see it, it is the opposite of unselfishness (unsalefishness being a virtue in our culture) and is therefore a vice.
Since both virtue or vice are encountered only in man-made cultures or societies (the artificial man-made world we call civilization), both have no meaning in the natural world, imo.

Without looking up a dictionary definition, I would say that to mnean it means something which is implicitly or explicitly beneficial. Evil, on the other hand, is that which is implicitly or explicitly injurious.
