Mr Sherriff's wife Jane said in a statement to the court she had launched a campaign to ban glass bottles and glasses from bars and clubs.
Addressing Charles, she said:
I will never let another person like you devastate another family. Your actions have devastated so many people's lives.
Mrs Sherriff said organ donations from her husband saved three other lives, but the lives of her family, including her two young daughters, had been ruined by Mr Sherriff's killing.
