The Hunt for Raoul Moat viewers were 'sickened' after watching the second episode of the ITV drama.
The three-part series explores the devastation caused by doorman Moat, who went on a shooting spree in 2010.
Millions tuned in yesterday, but were left horrified when revellers in a pub scene chanted their support for 'Moaty', who killed his ex girlfriend's partner and shot a police officer in the face.
After Moat (Matt Stokoe) declared war on Northumbria Police, Chief Supt. Neil Adamson (Lee Ingleby), was seen going for a pint, before being met with punters singing: "Raoul Moat is our mate, he killed coppers."
Viewers were fuming after the scene, with one tweeting: "Those people in the pub cheering for Moat haven’t one brain cell between them, idiots."
Another wrote: "I’m literally shocked people were praising Raoul Moat like this and singing songs glorifying him killing coppers ! Absolute madness and so disgusting. I hope those people are ashamed."
While a third agreed, saying: "Completely agree ! Literally have to be heartless to even make the situation into a joke. It’s sick."
Moat's murderous spree started when he tracked down his ex-girlfriend Samantha Stobbart and her new boyfriend Chris Brown, 29, over a decade ago.
He killed Chris after firing a shotgun through a window in Gateshead, while injuring Sam in the process.
Moat then shot PC David Rathband twice, in Newcastle, at close range, which left the officer blind. PC Rathband tragically took his life two years later after struggling to deal with his disability.
After a six-hour stand-off with armed officers, Moat killed himself.
The doorman's daughter Katelaine Fitzpatrick, 24, admits she's ashamed to call the killer her dad, and thinks the ITV drama will bring back more pain for everyone involved.
She told The Sun: "This TV series is going to bring the horror back.
"For many it will just be a crime drama on telly, but for me and his victims, and the family of his victims, this is our life.
"He was a monster. He ruined so many lives and I don’t think it will ever stop affecting my life.”
Moat's father Peter agreed, telling publication: "The biggest victims out of this are his children. They were traumatised at the time and this will traumatise them further.
"I have been in contact with his children and advised them not to watch. I told them it won't be sympathetic towards him."
*The final part of The Hunt for Raoul Moat is on ITV tonight at 9pm
