You'd think this was paranoid bullshit, until you start paying attention.
They'll do it. They have done it. This scenario that anon described is nothing compared to what has been done by Empire's Thralls to protect and expand its control. They have no problems committing horrific acts to use in Narrative Warfare schemes to gaslight people into slitting their own throats.
It's human sacrifice disguised as terrorism. Sacrifices have a purpose, and that purpose is to pay a blood price to gain the favor of a superhuman entity. The ritualistic aspect of how the Thralls treat the violence is the tell; it's not just a pattern, it's a script- a ritualized performance to carry out a ceremony in plain sight.
Watch. These slain people will be used to push evil ends, and once you see the ritualistic pattern you'll never unsee it. I'm not being hyperbolic when I describe this as human sacrifice; they are willing to kill to get their way, and gaslighting the aftermath is how they use these deaths.
Empire relies on human sacrifice to sustain itself. Civilization does not. That is the difference between the two. Empire must fall.
