Malevolent Creation

Disease ridden inhabitants radiate through the rest.
Healing mechanism triggered, genocide of the human pest.
Lives extinguished, disaster encountered, world's repossession, =
natural healing process.
Annihilate the living scourge, there is no coincidence.
Cataclysmic result, final stage commencement.
Return to dust, no more flesh.
The fate instilled, sealed with death.
