Star Wars: The Last Jedi director Rian Johnson has stated that Kylo Ren is not yet Darth Vader, a fact that angers his master Supreme Leader Snoke. In an interview with Entertainment Weekly, Snoke actor Andy Serkis explained the state of Snoke and Kylo Ren's relationship following the events of Star Wars: The Force Awakens.
“His training of Kylo Ren is not yielding what he wants,” he explained. “Therefore his anger towards Kylo Ren is intensified because he can’t bear weakness in others. Part of the manipulation is goading him with Hux and playing them off against each other.”
Snoke's inability to handle the weakness of others is likely a product of his own past. “The thing about Snoke is that he is extremely strong with the Force, the dark side of the Force,” Serkis explained. "He’s terribly powerful, of course. But he is also a very vulnerable and wounded character. He has suffered and he has suffered injury. The way that his malevolence comes out is in reaction to that. His hatred of the Resistance is fueled by what’s happened to him personally.”
