Who snapped his fingers and wiped out half of the world's population in "The Avengers: Infinity War"?

Thanos is the power-hungry villain the Avengers try desperately to stop. By the time the events of "Infinity War" wrap up, Thanos has obtained the infinity stones and done what he set out to do: wipe out half the population with the snap of his fingers. Many of our heroes disappear into dust before our eyes, leaving sadness and mystery in their wake.
