|You're the Diet Coke of evil. |
Just one calorie, not evil enough.
Thomas Aquinas tells us that good signifies “perfect being” and evil signifies “the privation of perfect being”, so when a thing lacks a perfection it ought to have, we perceive the deficiency as evil (see his Compendium of Theology).
Another important point is that evil has no substance, nature or being. We may say for example, Satan is evil, but the word "evil" is an adjective. Satan is not evil itself in the way that God is Goodness itself. Think of darkness; it is merely the absence of light. Darkness doesn’t come from anywhere or find its source in anything; it is merely the lack of something. No one can bring more darkness or take away darkness; one can only take away light, bring light or stop light from dimming. Once we understand all this, we can see that any candidate is a “lesser” in the sense that everyone is imperfect and the imperfection can be called evil. So we are really talking about the imperfection of two candidates or “the evil of two lessers”.
Of course, there is always a third party or a write-in candidate. This option reminds me of the contemplative side of Catholicism. A big part of contemplation is to be in the present moment because that is where we find God. The past is gone and the future does not exist; there is ONLY now. In the present moment there is no time to build-up a more perfect (or less evil) third candidate that can win. In our moment in the voting booth, we can only try to bring more good (more light) based on the candidates we have.
It is better to light one candle than to curse the darkness.
