Today I was walking at Horseshoe Overlook when I saw John speaking at the main campfire. As I never saw him telling stories, singing or speaking his thoughts and feelings, I decided to get closer and listen.
John told the gang members not to pick up a woman, because they would only get in trouble if they did. He expresses a hatred, anger and resentment towards Abigail. In the end, John adds that if he could kill her, he would. Arthur asked if things with Abigail were going well, and John told Arthur not to interfere in his life.
It's been a long time since I saw a RDR1 gameplay, so to confirm my thoughts, I accessed the dialogues from the mission "Bear One Another's Burdens".
Edgar Ross says:
"We've done this little deal for your freedom in exchange for all the men from your old gang. You gave us Williamson and Escuella. We still don't have Dutch van der Linde, but now we know where he is."
This means that Ross kidnapped John's wife and son so that John would hunt down his former gang members, when the Bureau of Investigation barely knew where all the members were. Also, I don't remember if Javier's prison was necessary for Abigail and Jack's release. So the deal was only for Bill's capture, because they didn't know where Dutch was and Javier might not even be considered.
