The boss is God. He gives Dennis one command. Not a lot of explanation because this is a test for Dennis. He must prove himself.
John who recommended him was the apostle. I think he thought Dennis would be up to the task as Dennis. But as you see, he didn’t seem to have a lot of info. He just does as he’s told and has complete trust in the actions of those above him.
Dennis had failed in a way before as seen by his flashback. This was his second chances at least that’s how I interpreted that flashback. Everything else is really straightforward but I’m not 100% sure on the flashback and the John thing.
Anyhow, the cliff that seemed like the end of the world was the entrance to hell. He saw it in the beginning and in the end when he killed himself.
Todd is the devil. Dennis had been living off the land God had provided for him but was bored. Dennis parallels Eve in the garden of Eden. Anyhow, he is persuaded to dine with the devil which is disobeyed the one command to not trust anyone else except the sheep-the sheep are lambs and they represent gods followers as well as innocence and purity.
The devil takes a jab at him by forming a question that assumes Dennis” relationship with his father is no good since he is disobeying the command. Dennis is clueless and doesn’t understand.
Anyhow the devil is having a laugh since he knows everything . He goes so far as to say his relationship with his dad is good and his dad sees him as an equal lol.
And then there are other references such as a deer dying by water when they consummate their unholy union-look up Psalm 42:1. and then Dennis saying he feels he’s being watched the more he desired Todd. And Todd completely lacking feelings for him but being satisfied with Dennis craving him. And then when the sheep are circled in the fence.
And then in a lot of media the injured leg is a reference to the devil.
He also says he’s never gotten hurt hunting at his inhuman ness.
Also like how he just toys with Dennis the whole time.
And Dennis fails his duty. Completely corrupted

So confused by the ending which smart ass wanna explain
