I mean, nothing changes. I can still see all those people; the fires don’t even appear on top of them. 
If y’all put in a “kiiiiiiiiiiiiill meeeeeeee” scene, it helps to be able to, y’know, kill it.
I was expecting something like a giant inferno so I looted everything and was ready to shadow strike out of there, but it only spawned a few boyscout campfires in the area - none big enough to even warm a human.
I was pretty disappointed with this as well.
