This comparison is stupid and dumb and also stupid. And dumb.
It's not saying Jedi do this or that, we're saying Luke wouldn't do it. Comparing him to Yoda is stupid. He's not Yoda. He's Luke. Same with Kenobi. You might as well say now that he's a Jedi he should talk like Yoda. That's not how characterization works.
That's beside the point that the situations were completely different. Yoda and Ben had been through the clone wars and seen the entire legion of Jedi decimated and now they were being actively hunted. They both attempted to thwart Palpatine and failed and Kenobi thought Anakin was hamburger.They had exhausted their options and now were depending on Luke.
That's beside the point that Luke is acting in ways completely contradicting his established behavior. He's willing to disarm himself and face both Vader and Palpatine simply because he believed Vader, the walking murder factory, could be redeemed. Then when he sees the dark influence on his nephew, the son of his twin sister and best friend that he helped raise, his first instinct is to murder him while he sleeps. Ridiculous.
Even after, he decides the best thing to do is to let his nephew be further corrupted by what he knows to be the most insidious influence in the galaxy. and leaves his sister and friends to face it alone. But not before leaving a map for everyone to find him because he wants to be left alone (lol).Because that the best thing to do is let the light die while the dark gets stronger and stronger...I guess? "Just go ahead and corrupt my nephew, kill my best friend, destroy what's left of the rebellion and nearly kill my sister. Because I am very butt hurt."
The only counter argument I've seen is basically "That's the point. Because it's later now and he's different. Because that's what happened in the movie."
