In Infinity War, Thor was stripped of his remaining family — his brother Loki — and rendered without a home as Thanos decimated most of the remaining Asgardians. He was a king left without a royal court. A ruler left without a people, whom Thor: Ragnarok determined were a person’s true home. As such, he seeked revenge on Thanos in Infinity War and became depressed amid these losses in Endgame.
