I read a topic about the people Trevor can take to the Altruist Cult to get the side mission where he has to shoot his way out. I read a few people had taken the lady that lives by the lighthouse and the guy that has been cheating on his wife to the cult. However, I've been picking these people up with Franklin. I'm guessing they're not character specific? I deliberately failed the mission with the golfer guy because I wanted to take them to the cult with Trevor.
I also heard some of them are better left alive? Which ones exactly?
