Sure but it’s not enough that they go through the motions and call each other liar/betrayer etc. I have no idea why Anakin believes what he does beyond the fact the story needs him to be in a robot suit after 130 minutes. Especially when some of the promises Palpatine fed him were so vague and outlandish.
The Thanos problem, yeah it’s similar. In some ways. But he at least does thing A to get macguffin B, and I see how that works. I don’t have to get over so many logic hurdles.
