It seems like the subtext in most horror movies is that the true monster ... is us. Normally, that's a heavy-handed metaphor for man's inhumanity to man, but sometimes that whole "man is the real monster" bit is a tad more literal. Take, for example, these five poor wretches ...
5The Demon King
The Byzantine empire was the Matrix: Revolutions of Roman empires: It made a ton of money and stopped some big invasions but wasn't much to talk about. (Also, Keanu Reeves was there.)
Michael IV ruled from 1034 to 1041. He was a peasant who fell in love with the empress (aw, that's sweet), even though she was married (aw, that's ... really not smart). Since Empress Zoe was the previous emperor's daughter, her husband, Romanos III, feared losing both his wife and his throne. The emperor asked Michael to swear on holy relics that there were no shenanigans going on, which he did. Silly Romanos! A peasant with the stones to ball the friggin' emperor's wife probably isn't afraid to break a sanctified pinkie swear.
Sure enough, in April of 1034, Romanos III was found dead in the tub. Cause unknown, but, y'know, not that unknown. Especially since Michael and Zoe were married the same day.
History's first twee murderers.
The new emperor, Michael, bribed the patriarch into properly crowning him, adding to his lousy reputation as a counterfeiter, adulterer, and regicidal boy toy. That's when Michael began bleating like a sheep, moving in erratic jerks, and hurting himself ... all things you might recognize from that exorcism movie that gets remade with a new title every year.

What was it called again? The Demon Be-gonner Guy?
Despite his efforts to conceal it, a lot of folks concluded that Michael was suffering from demonic possession as punishment for his sins. Although some historians considered him an "honest" and "brave" general who fought for the common folk against the nobility, Ioannes Scylitzes was not a fan, and further suggested that the empress's love for Michael was demonically influenced. By our count, he was at least three Game of Thrones characters.
The Boring Reality
It's often said that for every beautiful woman there's a guy who's bored of screwing her after he's murdered her husband and stolen her kingdom. Michael was that guy. Ignoring his adoring cougar wife, he struggled to rule amid epileptic fits. And just like all those crappy exorcism movies, epilepsy explains pretty much everything about this story.
4The Werewolf's Last Confession
Peter Stumpp had many aliases, which is weird, considering that he was pretty conspicuous (he was missing his left hand). Oh, and also because all of his crimes were committed in wolf form. How many canines do you know with alternate identities?
Now, witch and werewolf trials were pretty common in Germany in 1589, due to it being Germany in 1589. The only things to do at the time were farm, worship the devil, and make either sausage or war. Clearly, Stumpp was a big fan of those first three. But it was the brutal manner of his execution that put this story on the front page of the Syphilitic Holsteiner Gazette.
When caught and pressed, Stumpp admitted to eating livestock and at least 14 kids (including his own son), two pregnant women, and sundry German maidens.
Not a fun guy at parties.
Stumpp credited his master-level display of lupine dickitry to a magic belt given to him by Satan. But in a Faustian twist, the pumps that came with it didn't match! Curse your treachery, Beelzebub!
Stumpp perpetrated his crimes on countless victims for 25 years by exploiting the "killer in the woods" cliche. He practically invented Jason Voorhees' patented shtick, including the bit about waiting for the rest of the stupid teenagers to split up and go looking for their missing friend. But one day some hunters got the belt off of Stumpp, and then it was time for old-timey German country justice, as seen in this creepy paper animation:
The captured Stumpp was tortured with a breaking wheel, stripped of his flesh with hot metal pincers, and then had all of his limbs broken. Which, for the record, is about as dead as you can get, short of being ground into a fine powder, mixed into a power shake, and digested by fitness freaks with high metabolisms.
The Boring Reality
What if I told you that people don't actually turn into werewolves?
Stumpp was a Protestant in a part of Germany that had recently been returned to Catholic control. Torturing a fellow Christian, even a heretic, could be a dodgy proposition to explain before the Lord, but a Satan worshiper guilty of the worst crimes -- ah! That's doing God's work. Basically, the new ruler of the region made a bloody example of him.
But Stumpp confessed to prosecutors, right? More like persecutors -- people give false confessions all the time, especially while you're torturing them. And even if you don't confess, what's to stop them from saying you did? If you're still not convinced that Stumpp's conviction wasn't on the level, his mistress and daughter (who were known to be of good character, save for that whole Protestant thing) were also tortured, flayed, strangled, and burned.
It would be 400 years before Germany finally settled down and took up much more acceptable hobbies, like fascism and coprophilia.
