I don't agree with that idea. Normal children have the ability to develop a conscience and emphathy. Empathy seems to be something that we have an innate wiring for. It does require loving interaction with a caregiver to develop, though.

The idea that we're gradually turning into psychopaths because of a growing lack of "cultural indoctrination, sociocultural inhibitions, and legal authority" has no evidence to back it up. On the contrary, violent crime has been on the decline for many decades.
