He got iced by the authorities because his existence was most thoroughly inconvenient to the Communist Party that knows exactly how badly it has fucked up. They know what they did (i.e. authorized, funded, and supported the development of a bioweapon that ticks all the boxes any ILI who fully understands that "War" isn't really about killing your quote unquote "enemy" in droves would want to tick). Knows on top of that how history tends to unfold, ironically, because one term for it is the "dynastic cycle" because of, dun dun dun duuuun, their own fucking history that they never ever seem to learn from (much like the rest of the world but the extent of their records and how contiguous their "civilization" is/has been really leaves them absolutely no excuse even if compared to that titan of Civ, the "eternal city" that was "Rome" of all things) tells them exactly what happens next.
Maybe the others found themselves in similar situations. Too late, of course, to do anything about it given the factors in play at their time. Maybe that one Emperor figured it out but simply couldn't do what needed to be done to prevent the wheel of history from turning. Then there was that one Deposed Emperor who was the only one who managed to live to see the next one's coronation. Known for his absolutely obscene and downright offensive level of decadence, he ran and hid in a Buddhist Monastery. Chinese Saint Augustine. If only because he knew nobody in their right mind (from his perspective) would ever suspect such a thing would be possible and he apparently valued living more than... well all of that when posed the question by what amounted to his god. A "no fap ever again" challenge posed to record holder for most of those in a day. And he managed to pull it off. Hehehe, and people say us ILI's are stereotypical fedora tipping Atheists by and large.
I'd actually like to meet those idiots IRL. Bet I could show em' the light of Christ. Text is such a limiting form of communication after all.
