A few days late and not OP but they aren’t referring to that, but the scene further along where Luke cuts Vader’s hand off as he is down on the ground beaten and the emperor to push him fully to the dark side says something like “finish him” in his sinister tone. And then luke has a revelation where he was about to kill his father and the roles were reversed from bespin. Luke then chooses to not kill his father and threw his lightsaber down. Then gets electrocuted by force lightning and causes anakin to redeem himself saving luke and “killing” the emperor.

I believe that’s what they were referring too.

He was a robot in the Jedi temple. Dudes been around 1000s of years according to some throw away dialogue about him training younglings. It’s also crazy to think the movies really only take place over the span of like 80-100 years based on Anakin’s age at the beginning of phantom menace +lukes age in the Disney trilogy. The imperial empire was around for like only 40 years.

Technically star wars rebels introduced them.

It’s only eye revealing if you literally aren’t paying attention. Vader straight up chokes and breaks the neck of an officer, killing him, that he’s interrogating on the rebel blockade runner in the first 10 minutes. Stormtroopers destroy and burn uncle owens farm and leaves his and his wife’s corpses out in the open after burning them down to the skeletons. Han shooting first, Alderran is genocided by the death star, princess Leia is tortured, albeit it off screen, we get the scene of the interrogation droid with all his “toys” floating towards her before the door closes. All the pilots die including lukes best friend biggs fighting the death star except wedge luke and a few y wings, It’s never been a “kids” story till arguably the prequels when Lucas secured rights to toys and went on to push story elements that could be made into toys to sell.

Defederate from those ass holes, zuck can get bent and a whole slew of other bad things. Stupid ass hasn’t done anything of value and still acts like the dumb ass college kid bragging about getting people to give them all their personal details to use his crummy site.
