Spoiler Thread: Avengers Infinity War

One of the few things I disliked about the movie was the way they portrayed Thanos to be some ultra environmentalist. He bragged to Gamora how her home-world was flourishing because of the genocide he caused on her planet.

Thanos never wanted balance for the purposes of reducing the use of natural resources. In the comics, Thanos was nihilistic and was only seeking to earn the admiration of Death by snapping out half of all life in the Universe.
