I always viewed Padmé’s death as a self-fulfilling prophecy. Anakin acted upon his fear of losing her, and this is what caused her death in the first place. In this sense, I always thought it was a compelling death. Also, I am of the opinion that Leia’s mother being alive when she was still a little child was never a good idea to begin with, so I’m more than happy that the Prequels retconned it.
Sure - I imagine Lucas probably wanted Padme’s death to be an ironic self-fulling prophecy, like something out of a Greek tragedy, where a character tries to stop something from happening but then inadvertently causes that very thing to happen, because you can never escape Fate, etc. It’s like the pre-modern version of a time-loop paradox.
But I think Padme’s death doesn’t quite work as an ironic self-fulfilling prophecy, because Padme doesn’t actually die from anything Anakin does to her directly, but rather she dies mysteriously of a broken heart later on. Maybe it would have worked better if Padme actually died from complications during childbirth brought on by injuries she sustained when Anakin force-choked her.
