Avengers: Infinity War has the best ending in the MCU. After the snap, Thanos just goes to his farm and just chills. He doesn’t villainously laugh, he doesn’t think the Avengers were a bunch of no-ones, he actually respects them. He actually believed that he did the right thing. It wasn’t easy and he knew it wouldn’t be. But he thinks his sacrifices were necessary. The hardest choices require the strongest wills.
