10 Horror Movies That Forced You To Answer Impossible Questions

10. Would You Kill Your Loved Ones To Spare Them A Worse Fate? - The Mist

Frank Darabont's The Mist chronicles the efforts of David Drayton (Thomas Jane) to survive amid an invasion of Lovecraftian monsters upon Earth.

The film ends with David and a small band of fellow survivors, including his eight-year-old son Billy (Nathan Gamble), left utterly hopeless when their car runs out of gas shortly after driving past a gigantic, skyscraper-sized monster.

Humanity seems doomed to fall to the aliens, and so David and his fellow adult survivors agree to a suicide pact, to be spared the horror of being ripped apart by the creatures.

David ends up shooting the three other adults dead, but most agonisingly of all also kills his son.

Though the outcome for David is even worse - as before he can do himself in, he finds out that the military were literally minutes away from taking control of the invasion - the ending still offers provocative food-for-thought.

In a dire situation, could you bring yourself to spare your loved ones a potentially horrific death by "euthanising" them at your own hand, or would you rather wait for them to be torn apart by aliens?

Even with all hope abandoned, it's an absolutely impossible choice, and one likely to haunt you either way.
