In a twist of irony, however, doing so and becoming a god leads Death to see Thanos as her superior, and she is left still unwilling to speak to him (which leads the Mad Titan down a path of petulance and toxic masculinity).
Regularly shunned by Death, who isn’t even willing to speak to him, Thanos realizes he can help her complete her goal by collecting all of the Infinity Stones in the Infinity Gauntlet.
With so much else going on in Avengers: Infinity War, this would have been a sincere challenge to directly adapt, and the version on screen is not only a well-streamlined take on the narrative, but arguably a more effective one.
To provide a bit more background, in the comics Thanos is in love with Death, and because living souls have grown to outnumber the dead, it is actually her desire to see half of life in the universe killed.
