A trainee pilot bit two women and had to be dragged inside by his lover as he stood on a second storey window ledge and threatened to jump.
A sheriff expressed serious concern about Samuel Murphy's career choice after being told he is training internationally to be a pilot.
Murphy, 22, admitted carrying out campaigns of domestic coercion against two women which lasted for nearly two years in total.
Perth Sheriff Court was told that during the sustained campaign of abuse he spat at one woman when she confronted him about pictures of other women on his mobile phone.
He bit her - and also sank his teeth into another girlfriend who had to save his life when he clambered out of a window and threatened to take his own life.
Sheriff William Wood told Murphy: "Is he living and training in Austria as a trainee pilot as he claims? Presumably he will be subject to testing.
"I also think his temperament and emotional maturity will be tested," he said after it was confirmed that Murphy was in fact undertaking advanced training.
The sheriff told him: "You are a young man of 22 who comes before the court for the first time.
"Clearly a young man of considerable promise and your parents have been generous in backing your career up to this point.
"You really do risk all of that if you don't grow up. This is no way to run relationships.
"It is important you realise this is not the way ahead.
"Each of these young women had a grievance which they properly brought to the courts.
"It is to be hoped this is a blip and whatever is going on in your life you are better able to understand and deal with it without coming to the attention of the courts.
"I have some concerns as to whether you're temperamentally suited to your chosen career path, but that is a decision for others to take, having carried out appropriate investigations."
He placed Murphy under social work supervision for 18 months and made him subject to a non-harassment order to keep him away from his victims for three years.
Murphy, Kinnoull Street, Perth, admitted two charges of engaging in a course of domestic bullying behaviour.
Between 1 November 2019 and 31 May 2020 he told a victim he would kill himself if she left him, "became hysterical" when she asked him about other women's photos, struck and knocked her down, and spat at her.
For 12 months from 1 June 2020 he carried out domestic coercion against his victim.
This behaviour included clambering out of the flat window and forcing her to pull him back in before biting her knees.
Fiscal depute Andrew Harding told the court: "In November 2019, when they had been in a relationship a couple of months, [victim] confronted him over alleged infidelities.
"He said that if she left he would kill himself. They had an argument and the accused began to hit himself. He pulled his hand back as if to hit her.
"On 17 February when they were travelling in the accused's car she noticed he had photos of other women on his phone and she challenged him.
"The accused stopped the car immediately," Mr Harding said. "The accused grabbed and bit the arm of the complainer. The bite did not break the skin but caused the arm to be swollen and sore.
"Due to his state she did not trust him to drive so she drove them to his home. He was screaming and shouting and struck her on the body."
In May last year, they were sitting together when Murphy kicked her off the sofa.
He then stood over her and spat in her direction.
The victim fled, ended the relationship, and blocked Murphy on social media.
By 17 July he was in a relationship with [his victim] and blocking her from leaving the living room in the wake of a drunken argument.
"On 21 July, the complainer was staying with the accused. She left the living room briefly to get ready for bed. She heard a thump from the living room.
"She found the accused had opened the living room window wide open and was outside, standing on the window ledge. She went to pull him back in.
"She managed to pull him back in and closed the window," Mr Harding said, and added that she had then taken time off work to keep an eye on Murphy.
He tried to bite her on the hand, and then during October he pushed her over and bit her on the knees through her ripped jeans, before hurling a glass at her.
Solicitor Paul Ralph, defending, said: "He is an intelligent young man. But he has quite a lot to learn about relationships. This offending was unpleasant. I suspect he will have hurdles in future."
