Apparently the legal team didn't think so, and believes their client would have received less than 10 years if the AI tear-jerker video wasn't played. Even though the word "forgiveness" was used - they are probably right.
Okay this is the clearest read I've found. Regardless of the language, the real(looking) depiction of the victim carried so much emotional weight it heavily increased the sentence. I see this being a reasonable possibility and not legal games to get out of a sentence. Using an ai victim statement is playing legal games.
