What is the ruling on one who delays Hajj for no reason when he has the means and is able to do it?

A very common problem seen in youth in western countries is that their parents allow them to indulge in some form of haram in the hope that will stop them from committing worse haram. An example of this is that parents will say that they allow their children to indulge in music in the hope that will stop them from going out with bad people or leaving their home all together. Parents are afraid that if they enforce the law of Allah in their homes, that their children will leave. 

What is Islam's position on this sort of compromise? Some parents also say that they only have the duty to tell their children something is haram, and then their children have to choose for themselves because they are already young adults (i.e. 13 -18 years old and unmarried, living at home). Don't the parents have to forbid haram by all means, or do they just say that is haram and then leave them be? To what extent do parents have to go to forbid their children from haram?

Parents also believe that once their children reach the age of puberty they are no longer responsible for their sins or actions, and so say they will have no sin if they advise their children something is haram and then leave them. Is this true? Or do parents always have the responsibility of forbidding their children from haram, and will they be responsible if they see their children doing haram and just leave them after advising them?
