Any new scientific discovery should be explored to find benefits to mankind. Ethical issues must be developed and explored to ensure proper applications.
Human Cloning Experiment (HEC) is one of the failure projects like the Landsat 6 failure.
However, the meticulous studies are under consideration. The synthetic ways never replace the natural processes and phenomena. Science may take analogies from HEC.
There are many issues surrounding human cloning. Is there a need for cloned humans even if technically possible to do so? We need to respond to that question.
Still today, the scientific community fail to develop an animal by cloning having immunity and all other biological characters as totally normal. As human is a tougher subject, it will be far more complicated.
Cloning seems to me to be absolutely unethical and I believe that we should not go beyond the limit of the theoretical study of cloning. Each of us is unique and this uniqueness is determined in part by nature (from the combination of the genes we inherited from our parents) and partly from the socio-cultural environment where we grew up. A clone can have exactly the same genes as the "parent" but it is absolutely impossible that it is the same individual of the "parent" because the environment where it will grow will be very different from the one where the "parent" grew. Therefore it will be a very different individual from the "parent", ie physically could also be the copy of the "parent" but pscologically it will certainly be very different from the "parent" .
This concept changes its acceptance from one society to another in accordance with moral and religious criteria, whatever its positive outcome for man.
Human cloning is inevitable - I see no practical reasons that would prevent it from happening on any scale.
Whether we should perform it, is another question. At present, I see no reason to apply this to humans. But the offspring will have a mother, a father, as usual - and people endure far stranger upbringings with no ill-effect (adoption, etc.) - so I can see little potential for 'psychic' trauma from the revelation that they have the same starting genome as someone else.
