7 Billion Super Kill

7 billion super kill i wonder too about all this my idle mind goes into overdrive i think of the 7 billion humans the ruling elite may or may not kill off leaving just 500 million left alive they don’t need our taxes i was thinking 'sensibly' how they would do this? a virus is too iffy nukes too destructive/radioactive how about sending unmanned space probes to asteroids with spare engines put the engines on the rocks and fly them to earth all gps guided either say the rocks are for mining for recourses or just use them as a weapon to kill 7 billion my idle mind lol...
