Josef Fritzl will pose a threat to women for the rest of his life, according to a 30-page psychiatric report to be seen by the jury today.

Adelheid Kastner warns that Fritzl’s sexual obsession will never leave him.

“He has a malicious vein, an almost unstoppable flood of destructive lava,” wrote Dr Kastner. “He has a personality disturbance with narcissistic tendencies, emotional instability and emotional immaturity.


“Sometimes he is dominant with a sense of duty, and at other times he forgets his duty and is irrational.

“For somebody who was born to rape he held out for a relatively long time.

“He could not sustain friendships. The key role was played by his daughter. The relationship to his daughter in the dungeon is probably the most reliable one in his whole life.

“It is proved by the fact that he completely misunderstood the dimensions of his behaviour.

“He plainly assumed that when his daughter made contact with the outside world she would do nothing to expose the events which took place.

“He complained to her that he was an unloved child who fulfilled his function when he was born and was subsequently regarded, at best, as a calamity.”

Fritzl also suffered as a child from a condition which made him embarrassed about his penis.

Dr Kastner warned: “During the entire period of his crimes he was aware of his responsibility and thus his criminal liability.
