Q: Is obtaining organ donation from a death row prisoner in exchange of reduced sentence is ethical?  

 Answer: No 

It has been suggested to offer reduced sentence in exchange of organs to death row prisoners. But it raises many ethical questions. It may influence jurors, displace justice and manipulation of system by different parties involved. So far, the United Network for Organ Sharing (UNOS) and the Organ Procurement and Transplantation Network (OPTN) has not favored this approach.
