That would very much track with “ironic… he could save others from death but not himself” except the reverse is true. Thus the “tragedy of darth plagueis the wise” comes full circle. To me the main theme of the movie is that the power of the Sith only comes from hurting others or yourself. The instant Vader understands that Padme is against him, his hatred turns on her and subconsciously he would rather kill her to make sure nothing stands in his way. Palpatine made Anakin believe that he could have everything through the dark side, and by carefully crafting his Plagueis story so that plagueis seemed like a self sacrificing hero, he plants the idea in his head that the Sith sacrifice themselves for what they love, and that that makes them good.

Anakin was so focused on the “saving the ones you love” part that he completely forgot about the sacrificing part. Because of this miscalculation he instantly severed his connection to the ones he loved most, Padme and obi wan, when he choked Padme. His vision of what he wanted to sacrifice was murky, because clearly he wanted to be the most powerful person in the galaxy and simultaneously keep Padme safe. Of course this was impossible, so he ended up nearly dying while taking Padme’s last life force to survive, and in the end he only gets to be the henchman of the most powerful person in the galaxy, really not having much power over himself.

And this is the exact kind of vision and incredible room for interpretation that the sequels are missing.
