They fear they will no longer be able to control life and death!

"By the time the child grows up, the inverted search for a personal existence through perversity gets set in an individual mold, and it becomes more secret. It has to be secret because the community won't stand for the attempt by people to wholly individualize themselves.  If there is going to be a victory over human incompleteness and limitation, it has to be a social project and not an individual one.
