Maybe.
Good in a bad way or bad in a good way? 
In reality, good stays good and bad as it is. And many of us know what is bad and what is good.
However we just get relaxed and more understanding of life in general as we grow up.
Also since the younger age is no longer there, we start making our own decisions as to what level of good is acceptable and where the line REALLY needs to be drawn as opposed to what our parents or teachers like us to learn at early age.
We also become more brave in accepting bad to a certain extent.
P.S. Did not want to talk specifically about good or bad ‘girl’ concept.
