CRISPR-Cas genome editing technique, which utilizes the bacterial immune system, has significantly higher specificity and efficiency relative to previous techniques. It is used in a wide range of fields related to genetic engineering, especially is expected to contribute to human well-being and health. It has been used in a variety of organisms and cells ever since it was developed. But it can also be applied to genome editing of human embryos according to specific purposes.
Meanwhile, human embryos gradually develop with internal unity according to their own genome from the moment they were fertilized. A human embryo, as an individual of a human species, is a person with the nature of human existence. A person is dignified because it is the only being that cannot be repeated in this world, not because of some ability. Therefore, Human embryos are dignified individuals just like any other human being, so their life, the most fundamental value, must be protected. Also they should not be used as a material.
Then, genome editing of human embryo for treatment or prevention of genetic diseases seems ethically justified. However, there is a risk that CRISPR technology will cause unpredictable errors in the editing process, destroying the life of human embryo. Also, there is a problem that in vitro fertilization must be accompanied for editing.
Genome editing of human embryo for human enhancement cannot be ethically accepted. In this case, others instrumentalize human embryo according to eugenic thinking, and cause inequality.
Genome editing of human embryo for research can never be tolerated ethically. Because even if the outcome of the research brings enormous benefits to mankind, it puts the noble life of human embryo as collateral.
