So I decided to replay s1 of Wolf this past couple of days, and this time I decided to kill the CM before the trial. I have to say that it made the trial a lot more interesting and nerve racking than if you have the CM already with you.
Holly and Gren side with you to say you did the right thing. Snow and Beauty even come around if you say the right things. There is even a moment where you can leave the trial, but it felt too short. So I rewinded it so I didn't, and then Bluebeard comes around and sides with youl.
So in your next playthrough of s1, definitely try the trial with a dead Crooked Man.
