Learning Bioethics is far more complicated than understanding the four bioethics "principles" (autonomy, beneficence, non-maleficence and justice), or applying "situation ethics." Bioethics cases allow us to explore all of the complexities of the human condition and understand how ethics can be applied. Everything from human cloning, pediatrics, human subject research, genetics, issues of the brain, end of life, reproduction, etc, can be explored by reviewing and discussing bioethics cases.
Imagine a pilot trying to learn to fly. They might learn how to deal with difficult situations (wind shear, storms, instrument failure, etc) from a book, but practicing them in a flight simulator is far more helpful. Think of cases as the "flight simulator" of bioethics.
Bioethics are the ethics that dictate the rules or standards that would limit experiments in biology. Scientists are not permitted to try things just to try them. There are regulations directing the treatment of experiments and experimental subjects. Considering these on a regular basis is necessary to keep the rules in line with the current practices.
I think that the future will probably have a number of bioethical issues that need to be dealt with, which would mean that it is worth considering. Bioethics will be something that we will see especially considering new technological developments that have occured over the past several decades. We need it.
Yes, I do think that bioethics case studies are worth considering, and they play a large role in understanding how the human mind works, and how the people make decisions, using their ethics and different backgrounds. Some important findings have been found using these studies, so they are for sure worth it.
Bioethics case studies are worth considering because they combine two very important disciplines into one -- the treatment of living things with a Judeo-Christian view of ethics. Taking these case studies seriously produces a respect for animals, humans, the earth, and even further, for traditional values. We have a lot to learn from such studies.
We don't need more bioethics cases or case studies. Scientists trained in America are already taught how to be ethical with their work no matter what political dogma seems to be prevalent at the time. Bioethics case studies are worth considering, but we don't need to examine them too much.
