Is caused by mystery.
Throughout history much tension and even wars were conceived over one entity 'assuming the worst'. History continually repeats itself because one thing continually exists. Mystery.
When there is a mystery, people often want to know what it is. And when people want to know what something is, they start thinking about what it might be. They enter the domain of over thinking and before you know it, they're assuming either a doomsday dilemma or a fanatical fantasy. It's a bit like internal propaganda, you use emotions as leverage and let them run wild, driving the mind into doing things it would not normally do.
And yet people continually do this on a day to day basis. Quite often unintentionally, but nonetheless doing it. As much as I believe in the purity and strength of intent, accidentally killing a child whilst juggling claymores doesn't exactly change the fact that someone is dead. Likewise, driving people crazy, blaming yourself and driving even more people crazy doesn't acquit you of driving people crazy. Sure, you're guilty but like most emotions, it's a sense of motivation or a driving force, not a solution.
But then, can you really blame a person who unintentionally causes harm? What good does it do to imprison a person charged with manslaughter? Does the guilt mean they'll become a savior- a messiah? Or does it serve as peaceful retribution on behalf of the victim's loved ones?
No, it'll most likely just lead to more renegade emotions usurping rationality.
And the solution to this spiral of psychotic failure and ill fortune?
An anomaly in action from someone - anyone.
If no one is guilty, yet something bad happens, it takes a lot of effort for it to get swept under the rug. Yet if everyone agrees, perhaps the cyclic inertia might encounter some friction and stop.
Maybe if someone stops assuming the worst or stops leaving large shards of mystery around, everyone else may stop, re-contextualize and calm down.
Maybe.
