Was Natre capable of killing?
Having seen so many J-Horror and K-Horror movies, I have gotten very used to the violent vengeful ghosts, who will do physical harm to victims and kill them at any chance.
I don't know enough about Thai culture when it comes to ghosts, but it seemed like the writers of the movie didn't want to reveal whether or not Natre could actually kill anyone by herself.
What are your theories?
For example in the scene where Tun is chased by Natre down the ladder. What if he had simply let her catch him. Then what?
