'I have committed an act which should attract no pity, no sympathy, not even any understanding. I can't understand it,' Michael wrote hours after murdering his wife.
'That it was an effect, rather than a cause, bears no consequence. It was not appropriate, necessary, nor anything really other than pure evil.'
'The English language cannot describe my anger and rage. I cannot contemplate it,' the post continued. 'In the heat of the anger with Kerry's admission I had no control or influence over myself.'
Michael's, the former general manager of Royal Darwin Hospital, accused his wife of having an affair with one of his closest friends. This claim has been dismissed by coroner Simon Cooper in his findings.
Michael's was found dead in his Hobert jail cell.
He had pleaded not guilty to murder, despite telling police what had occurred on the day of the attack, News.com.au reported
