Ok, having finished the game yesterday, I'm still not certain what you're referring too. We may have had different outcomes. I finished the game with maximum honour, this is how my key final missions played out:
At the end of Chapter VI having rescued Sadie, killed Agent Milton who confirmed it was Micah who has been telling him about the gang's activities, I go back to camp and confront Micah about this and a Mexican-standoff ensures with Micah, his cronies, Dutch and Bill pointing guns at me, John and Charles. A bunch of Pinkertons show up at camp and start shooting at everybody.
John and I escape through the cave and when I am given the choice to go back for the money in the cave or help John, I chose the latter. I am mighty upset that my horse dies We head off up the mountain exchanging fire with Pinkerton agents on adjacent ridges. We come under a lot of fire and I tell John to escape while I hold them off. I then bump into Micah and get into a fist fight with him. My gun gets knocked away to the ground and I'm crawling towards it slowly when Dutch appears and steps on the gun. They exchange some words and Arthur dies.
Over the course of the second epilogue I ( now John) meet up with Uncle, Charles and Sadie and that chapter concludes with Charles, Sadie and myself heading off to kill Micah. Charles gets shot and Sadie gets slightly stabbed. Eventually I confront Micah and get into a shootout with him when Sadie turns up and pulls her gun on on Micah. A brief chat ensues then Dutch emerges from a nearby cabin and in the confusion, Micah grabs Sadie. I back and forth talk with Micah and Dutch and I convince Dutch to shoot Micah which he does, then I shoot Micah a few more times because he's still waving his gun about. Micah dies and Dutch leaves. Micah looks dead but I shotgun his head off just to safe and Sadie mentions that the cash and gold from the Blackwater job is in the cabin that Dutch just left. I grab that it (it's about 20k) and it's mostly game over.
Charles and Sadie both survive as you see them at John and Abigails' wedding during the closing credits.
Did you get the same outcome or something different?
Given Rockstar have remade a fair chunk of the map of the original game, which I'm still exploring, I would be both surprised and disappointed if we don't see a future DLC with Red Dead Redemption remastered/reimagined because it's such an obvious thing to do and it works as a 'sequel' in the sense of it being a continuation of the story of RDR2.
Your spoiler and ending was exactly the same. When I stated, "More to do with hope and karma I guess," I was mostly referring to Arthur's current state of being and life he was living.
Arthur was destine for death because of TB. I was just hoping for a better ending to Arthur's legacy. Something that could have prolonged his life longer, or maybe something that the Native American Chief and his tribe could have resolved later with some type of mystical herbal remedy. I wanted the ending to be more reflective of your choices (good or bad Karma), and that hope (longer life) for Arthur was based on those choices.
