wouldn't the virus->cure cycle either a) kill everyone or b) give people some kind of immunitySaladfork said:-Create a virus that causes death if an antidote is not applied at most a week after ingesting
-Add said virus in large quantities to every water supply I possibly can
-Only administer antidote to those who agree to live under my new rule
-Continue applying virus, make everyone reliant on me for antidote for the rest of their lives
-Everyone is now either dead or ruled by me.
and they could you know just take the cure
