The Last Jedi revealed that Snoke saw the rise and fall of the Empire, so it makes sense for him to see what Palpatine did and learn and improve, effectively enhancing the last great supervillain of Star Wars.
It’s been almost a year since The Rise of Skywalker, but one aspect of the sequel trilogy still leaves stars across the world. Supreme Leader Snoke was ruthless for Palpatine’s return while he was once poised to be the new Big Bad of the franchise, before we were given any kind of background story for him. A new theory argues though that the motivations of the towering villains ran a bit deeper than usual galactic domination stuff.
The Redditor theorizes that snooped Darth Sidious so much as Kylo Ren idolized Darth Vader. A love of Palpatine would explain Snoke much more than the gilt robes or the need for a dramatic entrance. The Last Jedi revealed that Snoke had seen the rise and fall of the Empire, so it makes sense for him to see what Palpatine did and learn and improve, basically up-holing the last great star wars supervillain.
This would also explain Palpatine’s confused line in Rise of Skywalker, in which he revealed he had “snoked.” Possibly this was not as literal as many of the others have interpreted it. Palpatine could have “made” Snoke of simple influence rather than cloning him as a clone.
