How about the one with the same sentences and the same identical post 50 times in the same bread? Bot or someone off their meds or in an otherwise drug/chemical-induced stupor?
I found myself wondering: What if you had two enemies fighting each other?
When convenient, you fight for either side, and then claim you are aligned with the opposition after you kill those you are sympathetic to. As the landscape morphs, you flip sides. As the clock ticks, the kill rate is maximum as you eliminate both adversaries. In the end, both are lying on the ground dying, and then you reveal to them your ultimate agenda; take the ultimate prize.
How do you do that without actually having to pull a trigger? Is it possible? Is it happening right now?
