This is not going to end well.
Neither of Harry's parents behaved well but they both loved him; now in his thirties with his own family he has everything he claims to want ; free of royal responsibilities, a very privileged lifestyle with the wife he chose to marry, an assured income and a new life, yet increasingly he reveals himself as bitter, spiteful and inadequate.
He blames his father ( for what, really?) yet his brother underwent the same trauma and is making something of his life, whether or not it is the path he would have chosen.
Estranged from his whole family and surrounded by people exploiting him for their own ends there is no -one Harry would listen who would show him what a pig mess he is making of his life.
The real tragedy is he thinks he is avenging his mother.
