We already have tons of terrifying sounding technologies. Almost every technology can be used in good and bad ways. We could use current gene editing to make super viruses that wipe out the entire world population. Gene editing has also given us the power to make way more food than we ever thought was possible. This new tech could create miracles for people with genes that harm them, like diabetes. Nuclear physics gave us the atomic bomb but also gave us an amazing and world changing source of energy. Staying ignorant of some science just because it could theoretically be used for something bad is never the right way to go. We have to learn everything and try to use it for the most good that we can. Plus I doubt this is something they could just randomly do to people. It’ll probably still be a rather complicated procedure only done in certain situations.
