A man accused of stabbing a Hobart shopkeeper to death a day after being released from prison was “unable to resist the final impulse to kill”, a court has heard.
Daryl Royston Wayne Cook, 36, has pleaded not guilty on grounds of insanity to murdering Voula Delios, 68, in broad daylight on July 23, 2016.
Forensic psychiatrist Michael Jordan told Hobart Supreme Court on Wednesday Cook suffered from schizophrenia and believed killing Ms Delios was “the right thing to do” as part of his plan to kill heathens.
Cook believed he was a member of the ancient Christian Knights Templar miliary order and that killing heathens would make him immortal, Mr Jordan said.
On the day Ms Delios died, Cook visited a Muslim prayer room in Hobart with an intent to kill heathens but left when there was no one there and walked to North Hobart.
Ms Delios was stabbed 22 times to the upper body while working alone at a grocer.
Cook suffered delusions and paranoia and could not resist the drive to kill a heathen, Mr Jordan told the court.
“Far from believing … it was the wrong thing to do, he actually thought it was the right thing to do,” Mr Jordan added.
Cook had been released from jail on July 22, the court heard.
