Wesley Joyce will donate a kidney to a total stranger to apologise for all the mistakes he has made in his life.
The 32-year-old was found guilty of GBH in 2004 and spent four years in prison.
He will now donate the organ to a mum-of-two in an attempt to give something back to the community.
Sally-Anne Grainger, 34, currently relies on dialysis three times a week to keep her alive. She suffered kidney damage from pills she had to take following a lung transplant in 2009 for cystic fibrosis.
When speaking to The Daily Mirror, Wesley said: "I thought, 'I must change.' This is a start. I can't have kids losing their mum."
The two-hour life-saving surgery is due to take place within the next few months.
