Good vs Evil

A thought to ponder: Is evil really the opposite of good? Or is evil merely the absence of good? Is dark not the absence of light? So is satan really the anti-christ or is satan just the absence of god like qualities? To go even further, does that mean there is a god, or just that god is a force, not a being. Therefore, if there were a god, would the god be perfect? Or would the god become satan because they lack the godly qualities? But then, if satan is the absence of god like qualities, is satan really a being? Or just the boogieman conjured up to take the blame for our own lack of godlyness.
