The homeless gamer accused of fatally stabbing a teen inside a Queens café during a fight over a seat was arraigned Friday on manslaughter charges – and his lawyer called the victim and his friends “thugs” as he blamed them for the horrific incident.

Alleged killer Paul Kim, 51, slowly walked into Queens Criminal Court looking stoic with his hands cuffed behind his back and sporting a bruise under his left eye as family members of 19-year-old victim Yangpu Fan starred him down.

Kim was arraigned on charges of manslaughter in the first-degree for fatally knifing Fan in the abdomen when an argument turned physical inside the K&D Internet Café in Flushing during a fight over a seat.

He went right back to playing after the bloody incident, cops said.

Judge Toni Cimino ordered Kim held on $75,000 bond or $50,000 cash bail.

Kim’s legal aid lawyer Kenneth Finkelman asked for his client to be released without bail and called the bail “outrageous.”

“This is outrageous. He shouldn’t be in jail while this is investigated,” Finkleman said, who noted that Kim found out in court that Fan was dead.

The lawyer said, “He was thrown over a computer before this happened…He didn’t know someone was injured. That’s why he stayed there.”

The dispute happened at around 10 p.m. inside the Internet café where Kim was a regular when the vagrant got into a scuffle with a group of Fan’s friends.

“These are thugs. In a lot of states, he’d be a hero. It was just one swing,” Finkleman said in an effort to make the case that his client was defending himself.

“It’s sad what happened. He is not to be blamed,” the lawyer said, claiming that Kim was punched with brass knuckles. “These people are at fault, not him. Anyone would have done the same thing.”

Prosecutors said there is no evidence that brass-knuckles were used.

Outside of court, Finkleman told reporters that Kim, who sometimes works as a cleaner, was “savagely beaten by thugs.”

“Of course it’s self-defense…[Kim] is not responsible for the person losing their life,” said Finkleman, who then appeared to blame the victim’s parents.

“Whatever circumstances led to this young man’s being that kind of a thug is why his dead,” the lawyer said moments after bringing up Fan’s parents.

Queens District Attorney Richard Brown said, “Senseless violence such as that which is alleged to have occurred in this case cannot be tolerated. As a result the defendant now faces serious consequences for his alleged actions.”

Kim faces up to 25 years in prison if convicted.

He is due back in court on May 12.
