Final answer:
Juror Nine's vote change should be based on evidence presented during the trial, not personal feelings, as fair jury deliberation is critical to the justice system.
Step-by-step explanation:
The question pertains to why Juror Nine changes his vote in a jury deliberation. This scenario highlights the importance of fair and impartial jury deliberation in legal proceedings. Jurors are expected to base their judgements solely on the evidence presented during the trial and not on personal feelings or prejudices. In an effective justice system, each juror must review evidence and deliberate carefully to reach a verdict, and any suggestion of pity or personal feelings should not sway their decision towards guilt or innocence. A vote change based on sympathy rather than the facts of the case could potentially undermine the fairness of the trial.
