“Families can be tough.”
In Avengers: Infinity War, Thor offers this wisdom to Gamora after learning that her adoptive father is the omnicidal titan Thanos. The horrors of familial strife are a recurring theme in the Marvel Cinematic Universe, being a fixture of the Thor, Black Panther, and Guardians of the Galaxy sub-franchises, but in Infinity War that theme reaches its darkest crescendo. Thanos is the compelling antagonist he is in no small part because of his children, and how his relationship with them is a pitch-perfect recreation of real-world narcissistic abuse.
