A homeless man accused of murdering a vicar told his victim to "die and hurry up" after fatally stabbing him, a court has been told.
Stephen Farrow, 48, is on trial over the death of Rev John Suddards at his vicarage in Thornbury, near Bristol, in February.
He was found by workmen with several stab wounds, including one which severed his jugular vein and another which pierced his heart.
Bristol Crown Court heard how Farrow gave a graphic account of how he killed the vicar during two assessments by Dr Tim Rogers, a consultant forensic psychiatrist.
"It was there in my head. I spent five days preparing when to go, what buses to catch," Farrow said, according to notes taken by Dr Rogers which he read to the court.
"I watched a man die. I have never seen that before - life ebbing away.
"It was always like it was meant to happen. He didn't fight, argue or nothing. My head wasn't there. I kicked the reverend to keep him down."
Dr Rogers recalled Farrow saying that when the vicar told him he was dying, he replied: "Die and hurry up."
The psychiatrist told the court how Farrow admitted watching DVDs and drinking beer at the vicarage after Rev Suddards' death.
"I find it abnormal in the extreme that anyone could do what they had done and sit in that person's home and behave in an entirely calm way," he said.
Dr Rogers said he does not believe Farrow is mentally ill, although he has all the "hallmarks of a psychopath".
"There have been times in his life that he may have been experiencing mental illness because of the drugs he was using," he added.
Farrow, of no fixed address, was not present in court after refusing to leave the prison in Worcestershire where he is being held.
Jurors were told he will not be giving evidence in his defence.
Farrow denies murdering Rev Suddards, 59, but admits manslaughter on the grounds of diminished responsibility.
He denies murdering retired teacher Betty Yates, 77, in Bewdley, Worcestershire, the previous month, but has pleaded guilty to a separate charge of a burglary of a cottage in Thornbury over the festive period.
The trial continues.
