Jack is debatable since he was the first to die, so he never had a chance to extend his rapsheet beyond simply following Alan’s orders. And yes, they did show Mark’s reaction to Jack’s death (specifically, we heard it). After Jack was killed, Mark casually obliged when Alan asked him to continue filming with absolutely no emotion in his voice. He did nothing to save Jack and didn’t give two craps about his death. And as you said that Mark wasn’t the only one who betrayed a crew member, I think you missed the point. I meant that by convincing Alan to let Faye die, Mark went beyond Alan’s orders and proved that he’s just as horrible as Alan himself.

Also, it’s not like Mark was being forced by Alan to do what he did. Mark was blatantly sadistic and bloodthirsty and was laughing his head off while burning the natives to death. In my opinion, simply calling him a henchman who follows orders would be an understatement at that point.
