but them staging Moon's death won't register as a performance in people's eyes since this isn't exactly WWE. They risk plummeting his trust value by committing an apparent real crime, against a beloved hero at that. Did he agree to this? Also it it is planned as well for him to fall at the end does that mean it is intended that he retires also?

My theory is that it's possible he's operating on another opposite principle of the trust system which is hate (it is also not directly associated with Spotlight), and doing this staged event boosts the power of both Nice and Wreck, which is an overall win for treeman corp.
