Eugenics has pretty strong connotations, but eradicating tay-sachs is also eugenics. Perhaps it could be thought of as positive & negative eugenics (like positive & negative rights)? E.g. killing people and telling them who they are allowed to marry and whether they can have kids is negative (taking away), while growing embryos free of genetic diseases is positive (giving)? Just rolling the idea around in my head. Of significance to me, if we had the capability to completely eliminate diseases like tay-sachs in a positive way (e.g. embryo selection), it might be inhumane not to.
