He was a simple man. At least he appeared so. As soon as the planet began healing he got sick. As more and more people got cured of their ills he felt less and less healthier. His morbid parasitic existence was not exactly sadistic but it was certainly dependent on causing misery to others. It was, as if, the God of Death was acting through him. Nobody could have believed that it wasn’t bats in a cave or bioweapons of mass destruction but this homunculus man living in a cave on an island who stopped the world in its tracks. Stopped the world economy from growing further. Those few who knew about him suspected so but what could they have done against the vehicle of Thanos except covering their nose. In the end, when entire village was healed, a miracle happened.
