10 Worst Betrayals In Horror Movie History

There are plenty of tropes synonymous with horror, including unmaskings, jump scares, creative gore, and last-minute revelations. But another theme that's rife in the genre is betrayal. 

When there's a serial killer on the loose and bodies start to pile up, it's only a matter of time before the survivors turn on one another. And when there's a horde of monsters closing in, some of the so-called heroes may desert their friends to guarantee their own safety. Also, twists often play a prominent role in horror, so it shouldn't be too surprising when one of the good guys has a sudden change in loyalty to save their own skin.

Over the years, we've seen treachery take many forms throughout the horror medium. Sometimes, the traitor in question was putting on a front from the get-go and always intended to deceive their friends. Other times, the betrayer tried to fight on the side of angels before desperation and fear urged them to put their own interests first.

Even though betrayal is unpleasant for anyone to experience, the following ten entries on this list took backstabbing to a whole new level.

Blade II kicks off with the Daywalker curing his friend, Whistler, of vampirism before returning to his base. While there, Whistler takes an instant dislike towards Blade's new weaponsmith, Scud. 

Scud is rebellious and confrontational, but seems loyal to the cause, especially since Blade saved him from a vampire attack. Or so it seems. 

When Blade discovers uber-vamps called Reapers have invaded the city, the titular character is forced to join forces with the vampire leader, Damaskinos. However, after the Reaper threat is quashed, Damaskinos double-crosses Blade, to the surprise of nobody. 

As Blade tries to blow the bloodsuckers up with a small explosive, nothing happens when he flicks the switch, with Scud then explaining that he programmed the bomb not to detonate since he was working alongside Damaskinos the whole time. 

What makes Scud's change in loyalty more hard-hitting is the fact that he allied with the same monsters that nearly killed him to betray the man who saved his life. Fortunately, Scud's traitorous turn doesn't last long, as moments after he spills the beans, Blade admits he knew he was a rat all along, before blowing his duplicitous sidekick to kingdom come.
