Thanos being the mastermind behind the Infinity Stone hunt throughout the MCU, in Phase One, he made a deal with Red Skull in World War II to search for the Tesseract, but Red Skull betrayed him to use the Tesseract for his own uses in Captain America: The First Avenger, in Phase Two, he made a deal with Malekith the Accursed to steal the Aether, but he betrayed Thanos in Thor: The Dark World, and already made a deal with Ronan the Accuser to gain the Orb, but betrayed him in Guardians of the Galaxy, he also made a deal with Ultron to gain Loki's Scepter, but Ultron betrayed him to use the Scepter for his own uses in Avengers: Age of Ultron, and in Phase Three, he makes a deal with Kaecilius to steal the Necklace of Agamotto, but lies and secretly made a deal with Dormammu in Doctor Strange, he also had a long time deal with Loki to kill Heimdall during the time of Ragnarok, because he possesses the Soul Stone in his veins as he peers into the souls of the Nine Realms, as a way of controlling them, but if Thor defeats Hela and stops the cycle that repeats Ragnarok, then he might keep the Heart as a way of living in Oklahoma, Broxton when Asgard might burn along with all the Nine Realms in Thor: Ragnarok, this is my theory
