Okay so weird thought that just came to me: Kylo feels a misguided compassion for Snoke.
Snoke blames his deformity on The New Republic according to Andy Serkis. We also know that Ben dealt with a neglect that he partially blamed on the cause of the Rebellion.
So this predator figure whose unfathombly strong with the force reaches out and befriends a neglected and confused kid. What story does he use to begin gaining sympathy ? Well, the story of an immensely powerful force user who is condemned and tormented by the New Republic makes perfect sense to use against a child who can probably see himself in that story.
I imagine that Snoke could weave a biased tale to Kylo. He would prey upon Kylo’s compassion for those who are similar to him. We see Kylo latch onto Rey against his better judgment simply because he sees vague hints of an uncommonality in her abilities.
That’s why Snoke has to surround Kylo with people who are not like him. He puts foils like Hux and the whole First Order next to Kylo so that he finds no commanlity and always turns back to Snoke. I think this is also a potential reason the Knights of Ren are nowhere to be found.
