'The light shines in the darkness, but the darkness has not understood it' (John 1: 5, The Bible). Life as it is is a choice, a choice between good and evil. For generations good and evil has co-existed on the Earth, within mankind. It has been a test man has never conquered; the evil within us. 'And God saw that the wickedness of man was great in the Earth, and that every imagination of the thoughts of his heart was only evil continually' (Genesis 6: 5). Hence, in The Lord of the Flies Golding uses biblical allusions to show the presence of good and evil within mankind.
Throughout the book Golding shows numerous examples of such, however the island, Simon, and the Lord of the Flies truly show that there is an existence of good and evil within individuals. Admittedly, the competition for grades might increase a student's achievement, rewards and their willingness to succeed. However students who observe that schools and classroom teachers define achievement primarily in terms of grades and performance are more likely to cheat and believe that cheating is acceptable. When students believe they will receive a benefit for doing well in class, such as getting out of homework or getting rewards from the parents, they will be more likely to cheat.
It is ironic that many students view the reward for doing well in the classroom as being able to get the reward by cheating. The point is that if the value of the reward is more important to the student than the academic task itself, the student may consider cheating acceptable. Furthermore, competing for grades has negative physical effects on a student. When a student begins to over study, he may begin to become very tired as well. When a student is tired and trying to study, he may resort to pills. The pills will keep him awake longer.
While he stays awake, he may begin to overeat. When overeating, he may become obese. Becoming obese may put a lot of extra stress on him. From this extra stress he may also develop ulcers too. Thus, when students begin to compete for grades, it has devastating effects on his body.
