Cloning one thing always leads into cloning something else. And don't think that cloning a human has not been tried, or even there is one living. Why? Think about it. Since it has come up, each government wants to know what their up against if another country decides to clone. Maybe super humans that can fight wars etc... In fact, I hear that even Hitler had his people look into this as well. So between that time and now, it's been done. And as long as we allow it to go on in some sense, it will one day become the norm. And who knows what diseases this may bring that the clone can't fight off for one reason or another. And when the non-clones become infected, it may be more than we bargained for.
