Passage Evil Can Most Accurately Be Defined as the Direct Antithesis

Passage
Evil can most accurately be defined as the direct antithesis of good.  However, when a human situation does not lend itself to clear designations of ultimate good and ultimate evil, or of right and wrong, then the best that one can hope for is to be able to make an informed decision about which course of action is "more right" and which is "more wrong."Consider the hypothetical case of Dr. Jones, who, in discovering the antidote to a poison (Poison H) has so far concocted only a single vial.  Now suppose that six citizens have drunk from a well whose water has been contaminated with Poison H, but Citizen A has consumed an inordinate volume of the contaminated water.  Accordingly, the doctor has only enough of the antidote to save either Citizen A or the five other citizens.It may seem clear that a doctor could not justifiably allocate the entirety of an antidote to preserving one citizen's life at the expense of losing five others.  However, suppose that Citizen A is the only patient currently present in the doctor's clinic, as the remaining patients are being transferred to Dr. Jones' facility by their respective physicians.  Citizen A is, in fact, Dr. Jones' longtime patient.  The doctor must therefore decide between two exigencies:  to save his own patient's life or to await the arrival of the five remaining citizens.Would Dr. Jones be acting unethically in sacrificing Citizen A given the prospect of administering the antidote to the remaining citizens in time?  This dilemma asks the judicious individual to take into account additional factors that might encumber his or her ability to save the citizens who have not yet arrived.  One should consider, for instance, how long each patient can survive without the antidote.  Unfortunately, no one has a crystal ball to predict future events.  A decision must be made in conjunction with the information available at the time.With this in mind, one may argue that the determination of good versus evil in making a decision lies in the doctor's motivations as he considers the consequences of his impending actions.  Imagine Dr. Jones' nurse exclaiming, "But the doctor cannot make an objective comparison between the lives of other citizens and his own patient!"  Yet, perhaps the doctor would be selfishly inclined to save Citizen A, as Citizen A is the only one whose death would be considered a grievous personal loss.But are such selfish human instincts then to be labeled as evil?  The same propensities labeled as selfish underlie characteristics classified as decent human virtues, such as compassion, empathy, and loyalty.  There are particular circumstances in which the doctor would indeed be remiss to the point of what could be argued as evil-as in cases where he opts to dismiss or distrust his individual conscience.  Consider the case in which he doubts his ability to arrive at a judicious conclusion and abdicates his responsibility for making this grave decision to the nurse.  Or consider the case in which he concludes that it is indeed more valiant to save the five citizens, yet fails to act on his decision out of personal anguish at losing Citizen A or to put an end to the ordeal.In such circumstances, the decision between right and wrong, or the moral dilemma, escalates into what is more accurately a personal determination of good and evil.  In this way, the relative construct of right and wrong, as determined by one's best attempts at logic and sense, must be subordinated to a moral imperative that may be said to be absolute:  namely, that one must abide by an internal commitment to what one has reasoned to be the right decision and follow a corresponding course of action in the allotted time.
-The author probably mentions the crystal ball to:

A) further define good versus evil in this circumstance.
B) highlight the importance of time in the doctor's decision.
C) undermine the doctor's ability to make an appropriate decision.
D) reinforce the uncertainty of the outcome.
