This is based off a post about how Lenny should have died, but it’s about Kieran and his death/potential survival. Rockstar kills off most red dead characters, and remember this is my opinion, so take this with a grain of salt.
Chapter 3:
Arthur is captured and is hung next to Kieran, Arthur breaks free because he is awesome, and is given a choice to either leave or help Kieran. If Arthur leaves Kieran, his honor is negatively affected and Kierans story is basically the same. If Arthur helps Kieran, he gets good honor and both escape but Kieran is shot. Kieran survives this but has a bandage around his arm for the rest of chapter 3 and half of chapter 4.
Chapter 4:
If Arthur left Kieran, the same thing happens, except the gang finds out and blames Arthur for his death, Arthur carries this guilt until he dies. If he is helped, he lives through chapter 4 and goes on to do the bank heist with the group.
Chapter 5:
Kieran gets trapped on Grauma and the chapter is basically the same but with Kieran.
Chapter 6:
Kieran suspects something of Micah, and sometimes gets mad or lashes out at him in camp, however the group ignores him and goes on. When the truth gets out about Micah, Kieran takes Arthur and Johns side. Despite what the player chooses, Kieran helps John escape.
Epilogue:
This is where honor comes into play. When John is heading to talk to Sadie, he runs into Kieran leaving the general store. The two talk to Sadie and end up helping her out. The chapter goes on with Kieran staying at the ranch for a while and helping Sadie and John. Kieran mentions being married and potentially having kids. During the final mission and showdown with Micah, Micah grabs Kieran instead of Sadie, this is the honor part I was talking about.
Bad honor ending: Dutch tries to shoot Micah, but misses and headshots Kieran. John is shocked by the death and shoots Micah(although the player does this). Micah dies and John and Sadie bring Kierans body back to the ranch to be buried. During the credits, a funeral is held for him and everyone at the ranch shows up.
Good honor ending: Dutch successfully shoots Micah, Micah lets go and shoots Kieran in the stomach, John kills Micah and Sadie and John bring Kieran back to the ranch. Kieran ends up surviving, barely, and Kieran stays at the ranch while he recovers. Kieran leaves the ranch in between red dead 2 and 1, his fate unknown.
In red dead redemption 3, the game would ask if players helped or left Kieran and whether or not they had good or bad honor at the end of the epilogue. If the player helped and they had good honor, Kieran would appear
Okay my opinion is out there feel free to disagree
