No matter if a person is born naturally, or in vitro fertilization it's not questioned if they have a soul. I see no reason to think otherwise towards potiential clones. On that matter though, I also think that aborted babies have souls and that it is a sick crime in our society to have mass abortion for the sake of having casual sex. If we got to the point of cloning humans for having kids, I assume it would be more expensive then in vitro fertilization, and would be mostly only used by those who who've tried everything else without success and can afford it.
Unlike in vitro fertilization, it's been suggestedeasrly in the clone debates that cloned organs could help medical emergencies. If human clones were used in such a way, and justified because they weren't considered alive, human, or having a soul, then the cloning industry would be just as bad as (possibly worse even) then the abortion industry.
Since then though, I think other attempts of growing organs without cloning have been made. From stem cell reasurch, to inserting human DNA in an animal fetus to grow to a certian age and then use the animal for the organ(s) in question. In my opinion both other option sound horrific, but no worse then other medical advances that have saved lives, so I don't know. I think with those advancements though, human cloning wouldn't become a viable resource.
