THE man stabbed to death by Tanya Doyle was "a lovely compassionate person" who cared for everybody he came in contact with in his life, his family said.
They added that Paul Byrne was portrayed in a certain way in court "that was very much one-sided and we wouldn't hold to that view at all".
Speaking outside court, Noel Byrne expressed his disappointment that Doyle had not expressed remorse for his brother's killing.
"We would like to refrain from passing any comment on her in particular. Her family, too, have shared in our grief," he said.
"However, we still don't feel that Tanya has any remorse, she didn't show any remorse in court and we were very disappointed with that.
"We are very happy with the verdict we got today. This has been three-and-a-half years coming and it does give us a certain sense of comfort.
"Unfortunately our plight isn't over, we will never have Paul back, but we're very grateful for the hard work and the effort that the guards put into this case.
"That telephone call has stayed with us, it's something we will never, ever, forget," he said.
In his victim impact statement, Noel said the family was disappointed that Doyle had not taken responsibility for her actions.
"As far as I know, she has yet to express even the smallest amount of remorse for causing Paul's death.
"If she felt remorse, wouldn't she have said to me or to my family how sorry she was for Paul's death and for the violent and brutal way in which he died?
"At the end of the day, she will have to come to grips with her own denial. If she doesn't, I would guess that no punishment that is handed out will be as harsh as the nagging guilt that she will never be able to get rid of."
He told the court: "I have not been myself since I identified Paul's body, listened to the 999 call and identified Tanya making the purchase of the knives with which Paul's life was taken. I do not think I'll ever be the same as I was.
"I know my life has not been the same. I had many sleepless nights. My dad would wake up in a cold sweat imagining how Paul died. Also my sisters have suffered the same fate."
He added: "The trauma of Paul's sudden demise on the eve of my niece's 21st party will have an eternal effect on us all.
"There is not a day goes by that I don't think of Paul and what life would have been like with him around," he said.
