Brent Martin was, according to his family and friends, a caring and trusting man.
Even when the 23-year-old - who had learning difficulties - was being subjected to an onslaught of violence, Newcastle Crown Court was told he did not lift an aggressive finger to his attackers.
The two teenagers - one aged 16, the other 17 - and a 21-year-old man who killed him have been warned they face a mandatory life sentence.
Mr Martin had spent nearly a decade in psychiatric hospitals and had only been back with his mother for two months when he was set upon while waiting at a bus stop.
He was vulnerable and the court was told the young men convicted of his murder punched, kicked and stamped on him for their own sport.

One of these youths told others: "I am not going down for a muppet."
This was, according to campaigners, a clear case of someone being picked on because of their disabilities.
Disability Now, the magazine covering disability issues, has put together a dossier of what it believes are disability hate crimes.
Disabled people targeted
Over two years it identified fifty-one cases of people with a wide range of disabilities being attacked. Detailed in this dossier are some truly horrific attacks:
Katharine Quarmby, news editor at Disability Now, was shocked by what she found: "I think it tells us that disabled people are targeted by a certain number of people in the population and they are seen as easy targets because of their disabilities.
Tougher sentences
"We need to increase the reporting of (these) crimes and we need the criminal justice system to look at disability hate crime far more seriously, to investigate it and prosecute it with far more vigour."
If an offence is labelled as a disability hate crime then the courts can impose tougher sentences, but campaigners say very few of these attacks were identified in that way.
The Equality and Human Rights Commission (EHRC) believes the attacks in this dossier are the tip of the iceberg. It is planning to investigate the matter further.
Neil Crowther, from the EHRC, says they may be able to use some of their legal powers to ensure much more is done to combat crimes targeting people with disabilities.
"We need to understand much more about why this is happening, why cases are not being reported, why cases are not being determined as disability hate crimes and then make a decision based on that," says Mr Crowther.
