Tyson Fury is still calling for harsher penalties for knife crime in the UK in the wake of his cousin's tragic death ... insisting officials should straight up castrate perpetrators.
The boxing superstar didn't mince words when expressing his outrage on talkSport on Wednesday ... demanding government officials do more to deter knife crime in his home country after his cousin was stabbed to death following an altercation outside of a bar earlier this month.
"What the government needs to do about this knife crime, anyone caught with a knife or stabbing someone needs castrating," the 34-year-old fighter said.
"It cost as a government too much money to house them in a prison. It costs them 50-to-60-grand a year to put these scumbags in jail. Castrate the little bastards. Castrate them."
Fury initially sounded off on the matter on his Instagram page on Sunday -- just hours after his relative, 31-year-old Rico Burton, was killed in Manchester.
Fury called for a big crackdown then -- but he expounded on it all on Wednesday ... saying people who are caught even carrying knives should be locked away behind bars for "5-to-7 years."

"We're supposed to be one of the safest countries in the world," he said. "But yet we can't go down the street with a watch on or anything because we're going to get stabbed."
"The government needs to make this tougher on these little cowards who carry knives and weapons."
He added, "What little scumbag coward needs to carry a knife around with them in our country?"
According to authorities, a 21-year-old man has been charged with murder in connection with Burton's death. It's unclear how much time in prison he's facing if convicted of the charge.
