Honestly interviewing the Bethesda crew is like rolling a dice anyway. The lead writer for Fallout 4 is Emil Paliguro. A guy who famously said regarding the late introduction on companions into the game and the obvious knock-on affect that had in-terms of underwriting the entire sacrifice narrative when you get a rad-proof companion right at the end of the game.
"So the story does kind of break down. But you know what? We knew that, and were OK with it, because the trade-off is, well, you get these cool followers to join you. You meet up with Fawkes near the end of the game, and it's true you can go right with him to the purifier. So we could've not had him there as a follower, and that would've solved the problem of him not going into the purifier -- because, at that point in development, that was the only fix we had time for. But we kept it, and players got him as a follower, and they seem to love adventuring him with. Gameplay trumped story, in that example -- as I believe it should have.
So if we'd planned better, we could've addressed that more satisfactorily. But considering how it all went down, I feel good about the decision we made there."

Their entire narrative was effectively nullified and they were okay with it. Bethesda can't write for shit.
