[Star Wars] Did Vader have cognitive dissonance that he became Palpatine's slave?

Or at least was aware of the full circle irony?

He was fully aware of his situation. There's a scene in the Darth Vader Marvel comic series from 2015 where Sidious, after trying and failing to replace Vader with stronger apprentices, goes into a long grandiose speech about how all the work the Sith had done for centuries had led to the two of them taking over the galaxy once and for all. When he finishes, Vader non-chalantly replies he knows Palpatine would have given the same speech to his replacement had his attempt been successful, but says it just doesn't matter. He's conscious of Sidious' backstabbing nature, he knows he's a dog on a leash, but the Empire and the Dark Side are all he has.
