"Marston encounters a strange man south of Mescalero, who seems to know a lot about Marston's past and claims to know him from his days running with the Dutch van der Linde Gang. However, the strange man is very coy and never reveals how he knows Marston.
He then asks Marston to complete a couple of tasks, both of which turn out to be moral dilemmas. And the Strange Man's tone hints at what course of action he believes Marston will take in each case."
Is he Marston's conscious?
The Devil.....or God?.......We'll never know.....
None remain who know~
I believe he's John's conscience. John is starting to realise how difficult the path towards redemption is and this man represents the new life he hopes to build for himself and his family and the easy, morally weak life he has led up until this point. He represents both because most people are neither good nor evil, but a thin mixture of both.
If it was a real morality test, John would have the possibility of being spared. But it's not and John dies either way.
The Strange Man is a manifestation of John's own troubled psyche, nothing more.
At least, that's my two cents
This is featured in my journal!
but he kinda gives me the effff
Yeah I'm leaning towards grim reaper/death too. He knows a lot about fate....
John: I'll let the proper authoriteies judge my morality.
Stranger: Oh they will, and they shall.
