Truth is a good thing. Too often terrible people in life become saints in death - for some reason people don't want to speak ill of the dead. I'm a believer of calling a thing what it is. Death never alters that. I say good for her for having the courage to say what was needed.
I think I've been around one or two of those type guys. My hat is off to the daughter for writing it like it was. Sorry the family had to endure that, but now they can have a happier life.
