Thank God the incident did not result in death.

That said, I believe this is a reflection of the larger society.
Who's responsible for bringing up a child, is it the Internet, house helps, T/V, teachers or parents?

Yes it takes a community to bring up a child but the primary responsibility falls on parents, all the others are playing secondary and supportive roles.

Sadly, situations have brought about a delegation, and in some extreme cases, a complete abdication of this responsibility to third parties and such an aberration is the backwash.
