Too bad your course does not use a Christian based text, such as Scott Rae's
Moral Choices.
Secular ethics courses usually focus upon teleological aspects of ethics, which are basically utilitarian (greatest good for the greatest number). Such a system is fraught with problems, e.g.,:
1. Predicting or measuring the harm or benefit of one's choices
2. Minorities are not protected
3. Egoism, or self-interest tends to dominate
All the typical secular sources of ethics, such as teleological or relativism, suffer from a lack of recognition of our one Supreme Moral Authority, God.
Scripture primarily teaches a deontological (principle based from divine commands and natural law) and virtue based system. The biblical basis for using natural law is found from verses such as Jeremiah 33: 25-26; Proverbs 8:22-31; Romans 2: 14-16; Proverbs 6:6-11, 24:30-34. Virtue theory holds that morality is more than just doing the right thing, focusing upon the moral agent acting (motives, character, such as being more Christ-like) more than the act the moral agent performs.
Biblically, virtues complement principles as equals. We have a moral obligation to be a certain kind of person, and whether or not this complementary view results in action is not relevant in many cases. Some rules require action, some rules require virtue. As Christians we do not see virtues as derivatives from principles or lacking in intrinsic value. Doing right is doing the right thing with the right motive and attitude. Doing the right thing for the right reason is insufficient if the right attitude underlying the action is missing.
Rae proposes the following steps for Christian based ethical decision making:
1. Gather the facts
2. Determine the ethical issues (legitimate competing interests or goods)
3. Determine what virtues/principles have a bearing on the case
4. List the alternatives
5. Compare the alternatives with virtues/principles
6. Consider the consequences
7. Make a decision
As to the scenario in question, some of the issues, not all of which may apply, to consider will be:
1. Human Life is God’s sacred gift
2. Innocent human life is not to be taken
3. Obligation to protect the most vulnerable in society
4. Death came as a result of the entrance of sin into the world (Romans 5:12, I Cor. 15:21-22)
5. Death is not part of God’s original design
6. But death is a normal part of a person’s life under the sun (Eccl. 2:14-16, 3:19-21, 5:15-16, 9:1-6)
7. Death is both an enemy and a part of life
If death is a conquered enemy:
8. Death need not always be resisted; for example, doctors need not always “do everything" for the terminally ill.
9. When the prognosis is poor, and further treatment is futile, death can be welcomed as the doorstep to eternity.
10. Making what is left of life more burdensome is wrong.
Your answer should be based in part upon what I have written above. Good luck!
