You have been downvoted, but this is a valid philosophical, moral, and ethical question. It is one that I myself have not come to grips with. One does worry about their own wellbeing, much less someone else's for which they are responsible for introducing to this world.

I believe that one answer to this is that life is meant to persist and that by introducing and teaching children that are able to enact change may be the world's best hope. One isn't going to stop humans at large from existing, so we might as well contribute to members that can help change the tide, teaching them modifications to human behavior that is more in line with nature.
