I'd be concerned that this phrasing would raise more sociopaths... because that's how they think about morality.
The quote doesn't talk about morality. I take it to be about social rules such as what is considered proper dress, table manners, rudeness and politeness, playing nicely, and so on. At a certain age (as WTP alludes to) children become capable of understanding above that level, and they will need a proper upbringing in what is good and real at that level as well. There's another quote of WTP I could give in this connection, but I've used up my quote quota for this month.

If you share it in a multiply nested reply to another comment then it is not included in the 'quote quota' - it's just the same as including a quote in any other conversation.
(ie. Your interpretation about applying to social rules rather than morality and ethics themselves seems right and I am interested in hearing the quote you have in mind.)
