Yeah. I nearly had the opposite thought. It felt like “wow why is the scene treating Luke like he’s this angelic figure?”
But then it all made sense when I remembered… “hypocrisy, hubris.” This is the Luke that island Luke looked back on and felt embarrassed by. Not because he was altogether wrong, but because of his pride.
Agreed absolutely. Why would Luke bother to force crush a dark trooper instead of easily cutting it up, if not to demonstrate his own power? (And yes, I know the actual explanation for that is ‘It looks cool’) The Mandalorian’s Luke also compliments TLJ Luke by showing Luke’s effort to find students, and his saying “I will give my life to protect the child” - when he ultimately, indirectly, caused the deaths of his own students by mishandling Ben’s training - makes his self-hatred over that more powerful. I only wish Dave Filoni would talk about TLJ Luke in relation to his appearance in The Mandalorian, that might shut up a lot of people.
