The Genetic Crossroads

You are a genetic counselor. A wealthy couple wants to use IVF and a new, safe gene-editing technology. They want to screen their embryo to eliminate a gene that causes a severe hereditary disease. However, they also want to use the same technology to enhance other traits, such as intelligence and physical ability. The law is currently ambiguous. Do you support their right to choose, or do you refuse to facilitate the enhancement, believing it crosses an ethical line?
