Is it possible that identical twins are genetically superior beings?

The other day, I was hanging out with a couple friends of mine who happen to be identical twins. As they are the only pair of identical twins I know who do not feel some animosity towards each other I know a lot of unhappy twins I will sometimes ask them questions about being identical twins. The conversation turned to genetics, as it often does, and one thing we were wondering about is whether or not identical twins are genetically superior.

It makes a certain amount of sense to me because the human body can abort a zygote or fetus that is “defective” so why not copy a fertilized egg that is superior? That way, if one of the people dies, there is still someone with the exact same superior genetic makeup out there and if both survive, there is twice as much superior genetic material as there would be otherwise.

I realize this is not necessarily an accurate hypothesis, just a musing from me and my friends, but I wanted to ask the question here to see if the collective thought it had any merit.
