The movie copped out

All through the movie there this ominous sense of this isn’t going to end happily, and then it doesn’t end at all. Instead it takes the easy way out and leaves the audience to surmise what could have happened, rather then dealing with the more difficult subject of the ramifications of Elvis’s actions.
What would happen to the pastor and his newly 'adopted' son, with all that Elvis has done and given the pastors devote beliefs?
I can see how with this option it defies audience expectation of a satisfying resolution, but it just left me feeling cold that this movie all the way through seemed to build up to something bad, something disastrous, and then nothing, like it didn’t have the balls to show what happened. It could have had another scene, one that showed how the pastors relationship and Elvis’s would have progressed/ended, or it could have gone for another half hour showing dissolution of his flock, dealing with consequences from maybe killing Elvis or putting him in prison, losing respect for god, his flock losing respect for him, the dissolution of a proud man when faced with an unimaginable atrocity. Whatever ark the story took, it could have gone down so many roads.
It did leave a detached, somewhat melancholic and pensive impression (which is the vibe throughout the film) and a definitive one at that, but for such a morally grim story it didn’t deliver on what it had promised throughout. It’s like it ended halfway through the 3rd act. What a cop out.
