Oscar Pistorius has said he thinks his girlfriend Reeva Steenkamp, who he shot dead, would want him to have a chance to redeem himself.
The athlete - who will be sentenced for Reeva's murder next month - has done an interview which will be shown on ITV at 9pm tomorrow night.
Pistorius has already been in jail for her manslaughter, but that conviction was overturned.
Pistorius said he does not want to waste his life by going back to prison.
"If I was afforded the opportunity of redemption, I would like to help the less fortunate," he said.
"I would lilke to believe that if Reeva could look down upon me, that she would want me to live that life."
Earlier this month, Reeva's father Barry Steenkamp told the South African court that her fatal shooting by Oscar Pistorius has "devastated" his family, and that he thinks about her constantly.
In a voice shaking with emotion, Mr Steenkamp revealed he has tried to imagine the horrific moment of his daughter's death, and said: "Oscar has to pay for what he did."
