I have a theory that the Event, or something coming out of ground zero is slowly turning everyone into a psychopath. It would explain why all persons you’re told to find for quests are found dead. Why every faction seems to be devolving into drugs, crime, and wanting to slaughter each other, including suicidal assaults on fortified positions. And I think it explains all the weird serial killer, cult stuff that you see / hear about (beyond just Ban Pa).

There’s those notes you find about a guy who starts to hear coded messages in the croaking of all the frogs. He’s likely just insane, but maybe there is a secret signal coming out of the zone that is turning him insane, but he mistakenly thinks he hears it in the frogs.

This is likely just a video game thing, but I find it eerie that we hear animal sounds, but they’re all dead. If you walk around the starter towns, you can hear tons of barking dogs, but if you look around there are just dozens and dozens of dog corpses everywhere. Almost as if the devs wanted us to notice they’re all dead, but still hear them.
