Wow. I never would have guessed we’d be debating whether or not Luke choked the guards. It always seemed completely obvious to me that he was choking them. Funny how that works.
As for the comparison of Luke versus Ben and Yoda… honestly, the way we ultimately see it presented in the prequels makes it very difficult to swallow what they did, and I find it very difficult to defend it outside of, “We need to tie up loose ends and get everyone to where they are in the first movie.” Honestly, the concept would have worked much better with the earlier interpretations of the Sith as a large organization of anti-Jedi. Then, with Obi-Wan and Yoda being the only two against a huge force of Sith, it makes sense for them to flee for their lives. But with the whole rule of two, it makes no sense. I mean, from Ben’s point of view, he just killed one of the two, leaving only the Emperor, and yet right then is the moment he decides he has to get away? I mean, in the original trilogy, Obi-Wan has to use obfuscation just to get past the stormtroopers on the Death Star. But in the prequel context, the Emperor’s clone troopers, the only other means of enforcement he has besides Vader, are cut down like butter by Obi-Wan and Yoda. They’re no threat at all. So rather than team up against the Emperor or leading a rebellion… they just go into hiding, leaving everyone to suffer at the hands of Imperial tyranny.
Honestly, Luke’s motivations seem extremely plausible by comparison.
