That would be imitating natural selection, not supressing it.
Supressing natural selection would be saving ill people, this seeks to eliminate them.
Just to note you can't really "help" natural selection along. Natural selection is less about strong traits overcoming weak traits and more about stable traits replacing unstable ones.
For example having recessive sickle cell genes make one less susceptible to malaria, but of course increases the likelyhood of producing offspring with the sickle cell condition. Many male birds have brightly colored feathers to help attract mates, but these also increases their visibility to predators.
I won't comment on the issue of genetic screening, but it is is not in line with natural selection.
