What makes it immoral? Nobody was hurt in any way, physically, emotionally, or financially. They disclosed the use of AI before showing the video. It even helped the perpetrator get a smaller sentence (IMO prison as a concept is inhumane, so less prison time is morally right).

Technology isn’t inherently good or evil. It entirely depends on the person using it. In this case, it had a very positive impact on everybody involved.

• Woman’s brother was killed in a road rage incident
• In preparing her victim impact statement for the court, she struggled to find a way to properly represent her brother’s voice
• Her husband works with AI and helped her generate a video of her brother for the victim impact statement
• The video was very well received and apparently true to her brother’s personality. Though she didn’t forgive the killer, she knew her brother would. So, in the AI video, “he” did.
• After all the real people made their statements to the judge, the video was played
• The judge loved it and thanked the woman
