In all the movies, books, etc... with this theme, the cloned humans are always sentient. The proposition here is that human BODIES would be cloned, but they wouldn't have developed minds. That means they couldn't feel happiness or sadness, or anything at all. Simply put, it's a way to create a lot of organs that could help save people's lives, without having to ask living people to donate their organs, or having to wait for someone to die and taking their organs (the two methods we currently have for getting organs for transplants).Toasterhunter86 said:Wasn't there a movie about this? I don't think it ended well.
