Avengers: Infinity War is filled with beloved Marvel heroes.
But the villain is the center of the film.
The movie is all about Thanos, the Mad Titan.
Could you say 'Infinity War' is a Thanos movie?
Without question ... Thanos happens to believe that what he is doing is right, and he behaves nobly towards that goal. But he will not stop until he achieves the goal because he believes that there is weakness that stands between him and the completion of the goal.
