I added Joe and Cleet and it seems like everytime I add the two as Arhtur's enemies you end up deleting something. In Dutch's eyes and mind he sees it as and believes that Arthur betrayed him even though that is not true. So from Dutch's view he thinks Arthur is no longer a ally or friend to him anymore but Dutch is wrong.
When I mentioned about Bill and Javier questioning Arthur and John's loyalty to Dutch later on. There are moments were Bill and Javier walk up to Abigail, Uncle, Charles and other surviving members of the gang questioning their loyalty. But those moments are so random you never know when they will pop up in the game. Bill and Javier even get mad at Abigail, Uncle, Charles and others when they think that they are betraying Dutch.
