Hello! I can also see how this could be something that he was really passionate about. But, I think that even if he thought that he was doing this for all the right reasons, there are still so many problems with taking such large steps in a secret way. I think that speaks to his hubris and the fame he was seeking. Yes I also agree that it was unethical because the gene editing effects not only the twins but their babies and their babies babies because he altered the germ line. I think that this could have been done slowly and with state regulation before growing embryos that would be effected with the results forever.
