DAE Do most of their playthrough in Chapter 2 and 3?

When I do a playthrough I'm RDR2 I have one goal: 100% the game. I love the story so much so that I can't even bring myself to move forward in the main missions and bring death and suffering to the people in the camps. First Sean at the end of Chapter 3 and the rest are doomed as soon as you come from the mountains. Since there are so many side missions and things to do after certain points in Chapter 2, I'll sit on the last John mission until I've collected literally everything I can and done all the challenges I can before everything is South of Blackwater. Does anyone else do this?

tl;dr I can't see my boy Arthur go out. I'll keep him limbo forever. Anyone else?
