First of all ethical issues are shaping our life even though we agree or disagree. Cloning is very dangerous issue because it causes to immortality which is against living organisms' nature. There are two type of cloning; reproductive and therapeutic cloning. These type of clonings are very different from each other. Cloning should use for benefit of living organisms. Otherwise it is going to be against natural balance.
Scientist clonned Dolly as a copy of entire sheep and they observe the results. That's done. Finish. They got the data that is necessary for the research. If they did not. They can do another clon. But if it is necessary for science. I cannot agree with reproductive cloning if it is making because of dangerous goals (which we can see in horror movies. Even though Ms. Deo feel boring :) while she was watching the movie "the island" it will be very beneficial to understand the bad effects of cloning). Naturally, embryo s are created only for reproduction and many people believe that using them for experiments is unnaturel and wrong. I am not against therapeutic cloning because it can be used to cure the individuals. If this type of cloning improve organ transplantation will decrease and individuals can get an original organ transplanation. It would be very beneficial for people who are suffering because of cancer.
