The overall goal of parenting is to provide a loving safe environment for children to develop into self-reliant positive contributing adults in society.
When it comes to jobs we usually judge people by their results. Even though most human beings make choices of their own accord it is still often seen as a reflection of how their parents raised them.
In other instances some people have different "moral codes" and therefore might judge a person as being a "bad parent" for allowing their children to partake in adult activities. More often than not there are two extremes: parents who are too lax and parents who are too strict or borderline abusive. It's a real challenge to be balanced.
There is no such thing as a perfect person or perfect parent.
