What we do, as writers, is give a piece of our soul to the reader, or at least we should strive for this. We tell stories that need to be told. We say things that need to be said, even if it is not popular or politically correct.
When that dad was cut off and shut out he sought court orders and was told he had no rights. Who knows if the child, who is now thirty, ever heard any other side or reasoning as to what happened. There was obviously no understanding on the part of the child as to the damage that would occur. Kids of that age don't have the ability to look so far into the future and weigh out the possible consequences.
