Can someone who is possessed force someone to murder?  

The Conjuring 3: The Devil Made Me Do It is a film that is "based" on a true story, by Hollywood standards.  Carl Glatzel, Jr., one of the sons in the family that the story is based on (but who is absent from the film) says that the devil had nothing to do with the murder of Alan Bono in 1981 according to an article on Snopes.com that was released on June 18, 2021.  

The book that the film is based on, The Devil in Connecticut by Ed and Lorraine Warren, says he did.  In the true story, David Glatzel's lawyers believed it so much that they tried to use it as his defense (unsuccessfully).  

Human nature, without any help from the devil, is totally depraved.  Check out Romans 3:9-18.  You don't need any help from fallen angels.  

Are demons responsible for murder?  It happens every day in a city near you.  Blood sacrifices are offered at Planned Parenthood.  But it's ok.  It's not all they do.  Go back to sleep.  

Considering how demons treat their host, it's perhaps more likely that they would murder them by suicide (Mark 5:5) than go on a rampage.  

But consider what Jesus said about the devil, religious hypocrites follow their murdering father (John 8:44). The devil was a murderer from the beginning, but he used words rather than violence. That explains why the Pharisees murdered the sinless Son of God, they shared a family resemblance with their father.  The devil encourages murder, and a person possessed is certainly not going to be goaded against it.

Like everything else Hollywood, something that is "based" on a true story is only loosely based on any given story.  So Conjuring 3 need not be taken as anything more than it is.

But wouldn't it be something if a faith based streaming service distributed a horror film based on a true story that was actually...true?  Wouldn't it be cool if you helped build that streaming service?
