This doesn't make any sense. First of all modern horror is less about spiritual horror and more with horror as analogy to issues in real life. Stuff like social media, parenthood and familial abuse.
The films the OP talks about are more 80-90s, but even in those good usually prevails at a great cost. And the notion that evil is powerful and pervasive is just the experience of most people in daily life.
Even in religious aspect you have texts like the book of Job that has him fall into misfortune purely as a point to be shown by god.
