What made me realise this too was seeing Endgame. Thanos with his population control, cosmic agenda could have been satire from an angry christian conservative who wanted to rant about climate change liberals and the club of rome or something.

It's really funny if you pay attention to villains in super-hero movies how often they're foreign or alien in origin with some environmental or grand agenda. Ra's al ghul is no different, and Bane of course who in Nolan's movie is the villian for bringing wall street down.

It's funny how loved these movies are usually by stereotypically 'woke' audiences when the moral of the story so often seems like something that could have come straight out of the 1950s.
