In his environment the only object which a man s will can love without any hesitation, is complete goodness. Were the objects that take man to God the only attractions, and were those which lead him away simply distasteful, there would be no problem. As it is, since God Himself is an imperative held only as a principle in the darkness of faith or as an inference in the light of reason, and since the objects that take man to Him on occasion prove more tedious than those which take him away, he is very open to deflection from his course. Along these lines the problem of moral evil can be represented as the problem of too many and conflicting goods. It is the general consensus of theologians that nobody chooses evil for the sake of evil.
Evil is more than a negation of good.
Evil is the lack of good when it should be present. As, for example, when a man is not considerate with his nearest and dearest. By another good elbowing out the due good, thus causing a man to forsake the good he ought to pursue for the pleasure of something else. In fact, moral evil is never an evil pure and simple, but, like a weed, which is a plant out of place, it is a good out of place. All this is said to help toward an impersonal appreciation that keeps the subject in proportion.
