Without even looking at the human issues, the underlying idea that you can improve a species by removing its biological diversity in favor of the “best” variant is catastrophically wrong.

Only for extreme cases. People who suffer more than they enjoy life.

In fact im curious many people say me thinks like this, i do this from an ethical point of view. Many people suffer through their life constantly bc of bad genes. If there were born without them the world would be better

  For one thing, the idea that there are “bad” genes stems from the outdated idea that there’s a one-to-one correspondence between genes and physical traits—but the reality is that most genes govern hundreds or thousands of traits, and most traits depend on similar numbers of genes. So bad traits usually result from the wrong combination of genes that are not bad in themselves—take sickle-cell anemia, which results from the wrong combination of genes that by themselves offer malaria resistance. (Most cases are far more convoluted than that.) If you remove the genes that cause the “bad” traits, you’re also removing the good traits they cause in other contexts.
