DHMIS has materialism that lets us understand evolution, historiography, bourgeois dicatorship, all kinds of things. Mad God lacks any real critique like those PMC Extinction Rebellion hackfrauds, it's just idealist libs crying about "the soul of humanity is ROTTEN" (don't ask questions of how and why things ended up this way, it must be God who hates us!)
ep 5 also has a similar "rebel attempts to go against the system and gets vivisected by a lunatic surgeon" scene.
at the time I interpreted this as a commentary on corporate advertising and children's media playing up ecological concerns while being uncreative about it and counterproductive
