" . . .those seeking the extinction of humanity . . ."
I doubt that whoever (or WHATever) it is that owns the cash crop called humanity (my guess is that the "royalty" would be considered local ranch managers) would allow such a thing ;)
While the end of the world is theoretically possible at any time, we know that for the last two thousand years, all claims (and there have been many recently) that the end is just around the corner have been incorrect, regardless of source.
Inductive reasoning would tend to dismiss such claims . . . until a better track record emerges.
