And this is why I do not Thanos is sympathetic, when confronted by the fact that his plan does not work, he decides to destroy the entire universe and rebuild it with people who will be grateful for his actions. That makes it seem like he is doing this for his ego, not for his supposed good intentions. Thanos is not pure evil, but he is not sympathetic either, IMO, there is a huge middle ground between those 2 points. Thanos is a compelling character, but sympathetic, I do not think so. He is a better person then Hela, Ronan or Ego the Living Planet, but that's an easy bar to pass. I would not deem up there with the really sympathetic villains in these movies (Two-Face, Dr. Octopus, Lizard, Magneto, etc).
