I think the main message the father was trying to convey to his daughter is to respect those who love you, or everything around you gets destroyed. This most certainly includes relationships. Trust is seldom ever given back to those who destroy it.
This father loves his daughter very much and to see her act so callously towards him and her mother shows she did not value them. So, taking something she "valued" and destroying it does not even hold a candle to the relationship she attempted to destroy with her parents.
The laptop can be replaced but you only get one mom and one dad. And .... mom and dad are not around forever.
"I know men and I tell you that Jesus Christ is no mere man. Between Him and every other person in the world there is no possible term of comparison. Alexander, Caesar, Charlemagne, and I have founded empires. But on what did we rest the creation of our genius? Upon force. Jesus Christ founded His empire upon love; and at this hour millions of men would die for Him."
