Of course any parent that really wanted to create a clone of themselves might have their own psychological problems that would influence the child anyway, regardless of the child's origin. Scientifically, an original and a clone would be similar but not completely identical. Their DNA would be almost the same, so close infact, that only a molecular biologist would be able to detect the difference. This might cause a problem if one person commits a crime and DNA evidence is used to arrest the clone. This means that two clones would have different retinal patterns and fingerprints.
Many people are concerned about a country making the ultimate soldier or the ultimate army.
Creating a super soldier would require breeding or genetic engineering. Genetic engineering is an entirely different issue from cloning and will not be discussed here. Making the ultimate soldier could be done through breeding today. Cloning simply makes this more reliable because once you create the perfect soldier you could replicate it to create an army. Making the ultimate army could be done today through drafting and choosing the most desirable specimens.
