Answer: According to reports, JJ Abrams had different ideas for each characters' story arcs while he was directing "The Force Awakens"; when Rian Johnson signed on as director for "Last Jedi", he basically decided to ignore Abrams' ideas and create his own direction for every major character, including Snoke. Since there is still one more film left in the current trilogy, though, we may learn more about Snoke's true nature in Episode IX; the possibility also exists that he may return as a Force ghost or in a cloned body, at least according to fan theories.

Answer: I know this caused quite the uproar with a lot of the fans, but looking back at the original trilogy, how much information was known about Emperor Palpatine when he was killed off? None of this was addressed until the prequel trilogy many years later.

Answer: He had to stay, to ensure the fleet would make the jump to light-speed. Finn knew the ship's layout and Rose was needed to disable the tracker. Poe stayed to convince Holdo that it was safe to use light-speed again.

Answer: There was no reason all three had to go. Poe was more useful staying behind and helping with the resistance.

Answer: Even if she is stronger, loyalty would also play a part in whether or not he would want to recruit her. Snoke probably knows that like Luke Skywalker, she would never turn to the dark side.

Answer: Snoke, like previous Sith Leaders, is a manipulator who wants to pit the other Force-powerful individuals against one another for amusement, to weed out any hesitancy in his apprentice, destroy potential rivals, etc. He knew that he would accomplish all of these by using Rey to test and torment Kylo Ren, but miscalculated Ren's own ambitions.

Answer: He is dead. Although a Jedi can still interact with the living as a Force Ghost, so expect to see Luke in Star Wars IX. It wasn't a hologram of Luke, he used Force Projection to be there. However, the act required too much energy and was too strenuous for Luke's body to handle, and the strain is what caused him to die.

Answer: Snoke had just insulted him for wearing the mask and belittled him for his feeble attempts to become another Darth Vader. Ben smashed the mask out of anger, feeling he had given everything he had to Snoke and the Dark Side by murdering his father and all he got in return was a rebuke for his incompetence in failing to defeat the un-trained Rey. The smashing of the mask was symbolic of Ben's decision to stop trying to be what he thought Snoke wanted and just be himself.
