Fear, guilt and shame as methods of moral instruction are seen as failures in decent parenting. If we were really convinced that using fear, guilt or shame as methods of discipline worked, though, we might be more ready to use them as techniques. But we aren't convinced that this is the case. We won't have more socially responsible people if fear, guilt and shame are part of their disciplinary diet as children. Instead, we will simply have unhappy people.
Responsible behavior has nothing to do with the traditional methods of raising moral children.
This doesn't mean that guilt isn't an important feeling. Guilt helps keep people on the right moral track. But guilt is a derivative emotion, one that follows from having violated an internalized moral standard. This is far different than making someone feel guilty in order to create the standard in the first instance. My wife once edited a magazine about hunger.
