Hot take (about 30 years after release): In Warhammer 40K, the Emperor is THE existential threat to the Universe, the cause of Chaos invading reality. The Empire is absolutely evil, destroys any human hope, and blatantly uses Nazi iconography. It's a crapsack universe, but even for that, the Empire is the worst.
So it creeps me the fuck out when I see people using WH40K Marine or especially Inquisition stuff for their art, and making them "heroic". It's the same as back in the day with sandbox wargames, that one guy who always played the Nazis, and sometimes cosplayed. Sure, he had a big set of Tractics minis and was a good opponent, but mayyyyybe we shouldn't encourage him.
