Everyone has to have feared something before. They need to know how it feels. When disciplining it helps too. I'm not saying that someone should keep a huge belt with them at all times, but if you tell them that they will get something taken away then it will keep them on their best behavior.

My daughter subjects herself to fear. She loves watching scary movies and I always tell her, "Don't do it. You wont get to sleep tonight." And she always watches and then she wont go to sleep at night. Children! ;)

Im not gonna say that they "should" be subjected to fear, but I sometimes feel that parents overly protect their children from their saught experiences. I was very much hooked on scary movies when I was young. The first scary movie I saw was Nightmare on Elm street, when I was seven and after that I watched all the greats and some of those movies are still my favorite movies today (shining, Exorcist, Rosmary´s baby and more) I did have a hard time going to sleep all up to the age of 13 I guess. But the kick I got out of those movies was worth it. I guess that children are diffirent and that what is ok for one is not so great for another

Of course. Unless we eliminated fear in adult life, only an irresponsible parent would prevent exposure to fear. Even then, we shouldn't remove that aspect of humanity. Plus, if you're a super-villain like me, you can make a decent living off it.
