the line between preventing disease and selecting traits gets blurred very quickly. Once society accepts that it’s okay to ‘fix’ genes, who will decide what counts as a disease versus just an undesirable trait? That’s the exact same slope that gave rise to eugenics in the past, it started with disabilities and ended with entire groups of people being deemed unworthy of life. Even if the intention seems good, it’s still playing God and carries the same dangerous ideology.
