All the responses in this thread clearly demonstrate the lack of knowledge certain people have towards "cloning".
Cloning IS NOT like in the sci-fi movies where you step into a chamber and an exact copy of you emerges; cloning is simply replicating DNA. A molecule. That's it. The replicated DNA STILL has to begin a zygote, cells must duplicate, and the BABY must GROW. We're not talking "instant man (or woman) - just add water!"
Cloning is no different than having and raising a normal child, aside from the fact that their DNA is not original.
"Creating deformed humans would be cruel and who takes care of them? Certainly you can't just euthanize, because they are human afterall."
Where is there a connection between cloning and the creation of deformed humans? Unless you clone already deformed DNA....which would serve not useful purpose. And even at that, normal reproduction is more likely to
result in deformations.
"By introducing man-altered genetics, you could open the population up to horrendous mutated viruses, bacteria, cancers or other organisms that could potentially spin out of control and introduce us to infestations and epidemics that could wipe out entire species."
I will acknowledge that this is a POSSIBILITY when talking about genetic modification. But this is about cloning, which is the exact opposite of genetic modification...
As for the "playing god" issue, I see it in two ways:
1) For those who believe in God, this is an ability that God has given us, therefore we have every right to use it.
2) I personally don't believe in god. That alone is my justification.
