Improving the gene pool - unethical?

Hello Valce
This is obviously, a highly controversial subject. Messing with genes is almost a taboo subject. For instance, religious convictions vs scientific theorys and experients.
The main thing I want to say about the gene therapy theory, is that it is quite possibly unethical.
It would be wonderful to be able to make a perfect world, but it really is an impossiblity no matter what approach taken by humans, as we are all imperfect, and the persons implementing the changes, well, who's to say that they would be perfect as well?
A world full of mean people would be the worst, period.:)*

Hitler thought this way too. He tried all your ideas on the German People. He was quite successful for a while. He killed the Jews because he thought Germans were a superior Race. Perhaps you should do some research on Adolf Hitler's Germany.
You might learn a few important things that would change your Life. Hitler did, and he's never been the same since!(Heil Hitler!)

Your stance assumes that negative traits are found by themselves. In fact, many mentally ill people are also creative geniuses and contribute far more to the world that "normal" people. Who is to say that a retarded person might not also carry a gene that might help us beat cancer or otherwise improve the gene pool? Would you want to be eliminated someday because someone decided that the world was too crowded and that your genes weren't good enough to make the cut? Beware of playing God.
