Example: A future astronaut is captured by aliens because of his own stupidity. They are going to take pieces of his genetic code and create thousands more like him which will have most of his memories, etc. and be within 25% of being him exactly, and they will live like kings. This process will take a day or two and will be painful, and might cost him his life. Does he have the right to escape and deprive these potential lives of being created? If he escapes before the process is complete all of the thousands of new lives will die instantly.
