i think it both the child and parents, sometimes some parents are too strict, others to are too calm and both make the children try to take certain decisions when they have the free time, and I think it the choices the child makes during those free times, no-one intends to make bad choices but sometimes we want to explore and experience things for ourselves and we find ourselves where we are not suppose to, doing things we are suppose to,
All the same I think it just the grace of God that makes one good
