I don't see any way that RJ is a group of people (like the whole list). RJ is a serial killer that kills people for, among other reasons, talking bad about him on TV. IMO the only way a group RJ works is if everybody they kill is for political reasons or to protect the group but we already know that isn't the case because what would be the purpose of killing PJ's family, the reporter, etc. RJ has subordinates, disciples and friends but IMO the man himself has to be a person not a group.
