I always ending up siding with Joshua Graham. Mainly because it seems like the other guy (david?) is just doing a really basic “noble savage / white saviour” routine. Like his “solution” is to just pack up and leave in order for the people to preserve some inherent quality of “innocence” he thinks they possess. He would rather have them hounded for the rest of their existence, than do something that challenges his perception of them.
On the other hand Joshua Graham is a mormon
It’s one of the weaker DLCs but just wandering around Zion is so much fun, it’s by far the prettiest location in the game. Even if the story sucks I always make time to visit every play through just for the scenery
