Palpatine's key flaw is essentially "evil cannot comprihend good" combinied with not accepting that he could loose, Palpatine's actions in ROTJ make perfect sense from what we've been told of the Sith philosophy which is ultimately power and dominance for its own sake.Straha wrote: ↑2019-08-30 12:33pmI don't think he broke things because he could. I think the best in-universe explanation is that he broke things because he genuinely didn't care. He's won power, he controls the galaxy, and... what's left? He's a dog who has spent his life chasing cars and finally caught an Abrams Tank, what is there left in life? He seems to get joy out of sadism and using the force (especially to kill Jedi), but beyond that? Solid 'meh's all around.Elheru Aran wrote: ↑2019-08-13 05:21pm I find it somewhat of an unusual approach, given how the EU depicts the chaos and infighting of the greater Empire. I suppose encouraging discord and rivalry is the Sith way, but it's no way to run an intergalactic government. It's like, after he assumes the mantle of Emperor, he began deliberately breaking shit everywhere because he could. Appointing all the wrong people because they kissed his wrinkly ass just right and all that. He got lucky with competent guys like Tarkin, Vader and Thrawn, but on the other hand we have guys like Ozzel and Motti... eh. Expanded universe, what will we ever do with you.
It explains his lazy planning with just rebuilding another Death Star after the explosion of the first one, and why in RotJ the only thing he seems to enjoy is tweaking Luke, watching Luke and Vader fight, and then torturing Luke.
And, to touch on the 'maybe he's a master manipulator with deep insights into people's minds' thing: Vader is someone Palpatine turned to the dark side by planting images of his wife and children dying, is someone whose turn he cinched by telling him Padme died along with his unborn children, and someone who Palpatine controlled and cajoled by having him search for the Son of Skywalker. And what does Palpy do directly in front of Vader after a climactic battle? Torture his son in front of his eyes with force lightning. Those are the actions of a man who just does not give a crap, not someone who is an arch calculator.
So Palpatine doesn't see Vader's betrail not because he no longer cares for anything but rather he's unable to understand that there's a part of Vader who would put saving Luke above gaining more power, even if saving Luke would cost Vader his life.
