Thanos
In Infinity War, Thanos is on a mission to scour the galaxy and destroy half of all life to make sure no one has to go without. He’s done so by traveling from planet to planet with his army and the Children of Thanos ... but he could save a lot of time and energy by collecting the Infinity Stones and literally snapping his fingers to get the work done for him. It’s a solution to a problem only he sees — or, as he points out, one only he has the will to take responsibility for.
