I totally agree with Spyder and Asimir. And yeah, exact twins are sort of biological cloning, that's the example I like, too. Very Happy
If some mental characteristics and some psychology is determined by genes, someone could clone Hitler. Or, worse! Genghis Khan!!!
Moral reasons? Ethics? Well, it's the same thing as having a child. Don't tell me people shouldn't have children because it's unmoral for the children, which are born and have their lives ruined. Same with clones. You don't choose whenever you want to be born or not, same with the cloned persons.
You say only God has right to create life? Well, we all do, WE procreate, not God. And maybe he is the only one who can engineer life as it is? Well, genetic engineering is propably some form of "breeding" that is nowadays done with dogs or horses, except it's far more predictable (you don't have to wait for a horse with good genes to be born, you simply design it so)
Aaah, and cloning would ruin horse riding, because using DNA from single hair piece of best arabian-blood fastest champion you can clone yourself the same one.
Or, will normal people laugh over the cloned ones? Racism and anticlonitism? Lol.
