Brian McTaggart, a 53-year-old monster who r*ped his own son and his wife over 900 times has been described as 'more evil than the devil'.
According to a report b The Sun UK, Brian McTaggart attacked Kathleen McMurchie up to three times a week during their 10-year marriage — and battered their lad David, 31.
The beast, from Dundee, destroyed the lives of 18 victims during a 24-year reign of terror.
Sickened David, who waived his right to anonymity along with his mum, said: “He’s worse than Lucifer.”
David, 31, insisted the monster should never be freed following his conviction.
Evil McTaggart threw a hairdryrer into her bath and hurled her down stairs during their nightmare 10-year marriage.
After his dad’s conviction, David — who the fiend was also accused of raping — said: “He’s an animal. He’s completely switched off from the world.
“I’ll never be satisfied while he’s still alive but I’m glad he was for the verdict. He should never walk the streets again.”
David, who waived his right to anonymity along with his mum, says the predator “ruined his life” and revealed he bathed in bleach after the alleged abuse in 2011.
He went on: “He was volatile. He battered me as a child but nothing homosexual until I told people I was gay.
"He raped me when his girlfriend was sleeping in the other room. I was hysterical.
“I spent eight hours in the police station that night then I went in for a bath with bleach in it, I still do that to this day.”
During his father’s trial at the High Court in Glasgow, David told jurors: “When he opened a bottle of vodka he changed. He behaved as if he was possessed by the devil.”
David, of Blackpool, is battling an eating disorder in the wake of the trauma.
He suffered injuries aged 12 to 18 after his father rained blows on his head and stabbed his fingers into his eyes.It total McTaggart was convicted of sexual and physical abuse against 18 victims in home city Dundee between 1980 and 2004.
Jurors heard the fiend told victims: “You belong to me. I can do anything I want.”
Ex-wife Kathleen McMurchie, 53, told the trial: “He r*ped me two or three times a week over six years. He also raped me shortly after I had given birth.”
The mum — who divorced the brute in 1993 and has remarried — said McTaggart would say sorry and buy her flowers after the violence.
Jurors heard how another r*pe victim was choked and her head forced under water. A third was attacked four times as she slept.
McTaggart indecently assaulted girls and boys and physically abused women and teenagers.
Charges of raping a fourth woman and David were not proven.
McTaggart claimed he was the victim of a “witch-hunt”.
Judge Lord Mulholland placed him on the sex offenders register saying he treated women as “punchbags”. Sentence was deferred.
Police branded the brute’s reign of terror “horrific”.
Detective Inspector Muriel Fuller blasted McTaggart over his warped abuse which spanned two decades.
The Domestic Abuse Task Force leader said: “McTaggart was a prolific, serial domestic abuser.
“He abused numerous partners, however, his offences are much wider and include the sexual and physical assault of children.
“His catalogue of offending is horrific. It spanned years and affected the lives of so many.”
Det Insp Fuller, right, also praised the courage of victims who helped nail the monster.
She added: “It’s only through the bravery of his many victims and witnesses in coming forward and disclosing the many offences he committed that he’s been convicted.
“We hope the outcome encourages more victims to come forward.”
