Parents are responsible .. up 2 some extent
If they are giving proper time and guidance from the beginning , a child can hardly be ruined
I have seen my self a Family Fully religious ( so religious that they have Daras at their place ) but still one of their son has turned so bad that he is into every bad thing one can of think about
In my view - you don’t have to get tooooooo much busy in your personal commitments that you stop caring about your children.
Being a Parent you need to at least keep an eye on your child until you feel his is responsible enough to carry on from now on.
