Warfare back then was pretty different too. It wasn't just killing. It was raping and pillaging. And if you know your history the Templars were accused of worshiping a devil, Baphomet. For reference, Devils are fallen angles, not demons. Demons are spirits, not to be confused with a soul.
Angels, genius, are of a higher order that connect men. They're a mindset. A genre. So a fallen angel is basically a mindset that disconnects men.
Translation: The templars were corrupted. Likely, by opium or some kind of drug they picked up in their raids, and they let their addiction drive them. Losing touch with their vows, going beyond what was necessary. Although there were likely those who just enjoyed killing Muslims, or raping innocents - they justified it "I'm a solider fighting for a cause." "for us", but really it was just for their own satisfaction.
"Addiction" wasn't part of their vocabulary. Thoughts, dreams, and emotions, were Angels, and spirits. On certain drugs people claim to experience "the god head" where...no, I'm getting off topic.
Fujoshi, is where a girl imagines if STRAIGHT characters in EXISTING MEDIA were gay, or had private homo-erotic experiences. The name comes from spoiling or rot. It's distinguished from original homo-erotica and fanworks of already gay characters.
I'm pretty sure Supernatural is one of those shows that only girls watch which gets a lot of porn. Along with Full Metal Alchemist. and Kingdom Heart - Specifically Organization XIII members.
There's a narrative theme that connects all of them. But I don't have the space, the time, or a strong desire to explain what they all have in common that attracts the fujoshi fanbase. To be clear, fujoshi is not a person. The word means "rotten girl" you should add -ness. to the end. Like gay vs gayness. It's a collective noun, not a adjective. Like brony or trekie. Where brony has "bro" in the name, it doesn't apply to just men. That's the fu in fujoshi. But with playful kanji.
