In Harry Potter , lies do not produce bad consequences. As a matter of fact, the author seems to just be easing the reader into the idea of lying, because it develops later that all the kids at the Hogwarts School of Witchcraft and Wizardry lie like rugs. As a matter of fact, the climax of the book occurs when Harry must successfully lie in order to save his own life. So it seems like a fair interpretation to say that lying may even be good , at least in the Harry Potter series. Now, my kids are no angels, and they do tell lies.
Most kids lie.
Maybe all kids lie. But at least my kids know that it is wrong to lie, and I think they experience a sense of guilt when they lie. This, I think, is healthy. Lying without guilt as seems to occur in Harry Potter is not healthy. Then there's the stealing.
