Yeah, I think it would be a crime to kill a human clone, but that's not the main emphasis on cloning these days. It's all about cloning organs, not humans. First off, it's expensive and has a high failure rate. Second, it raises a huge ethical problem. Third, by the time it takes to clone you, you might be dead from whatever problem you had by the time the clone grows old enough to "give" you the organ. No, don't worry about cloning humans. It's all about cloning organs. ADD: If it looks like a sheep and acts like a sheep, it's a sheep. Who cares about what it's thinking if we can get human organs from it?
