I’m an artist and student of arts and history of arts, etc. Most of time, portraying decadent elements makes the watcher to be into deadly desires and be more fanatical to serve, I have no source here, but the more you look at this elements, you’re gonna see it. Then, there’s also chantings about accepting death and causing it, causing a run of adrenaline and even oxitocine/dopamine on it. There’s a famous Christofascist song in the Spanish army called “I’m Death’s boyfriend”, which os sung while carrying a Jesus or a Virgin Mary on a pole.
