Families are never torn apart by American immigration law. There is nothing in the law that prevents an American citizen from leaving the USA. If they won't leave, then that says something about how much they value the family.
You could make a similar argument for any crime that results in prison time. Locking up murderers results directly in human misery and torn apart families. This case is far more severe: we don't allow the family to move into the prison to live with the criminal. We even separate nursing babies from their mothers.
