Is There a Moral Objection to Using Crisper on a Sperm Line?

Right now, there's essentially a moratorium on doing these kind of germ line experiments in humans. Although it seems to me, morally, there's at least some cases where i don't see how any one could ably argue against it. But going forward, could we imagine a time when there would be applications where germ line editing might make sense? I think yes. I just think tha we have to be again, very thoughtful and cautious about it.
