The latter is what I would prefer. I do love how Lucas used Anakin’s fall to have themes about the dangers of clinging onto someone too hard and not being able to let go. But I also think that having an added layer of Anakin’s unwillingness to accept his own mortality as well would add more to it.
Because you’re having a man literally slaughter his entire adoptive family. Going against everything he fought for and valued. His reasoning for turning should be multi-layered.
I feel like that’s a lot of the reason people cling to the “Jedi were ideologically flawed and Anakin was getting revenge on the Jedi for forcing him to repress his emotions” head canon when George Lucas literally agrees with the Jedi’s philosophy (and says they’re allowed to love and all that) and only blames Anakin’s greed and Palpatine’s manipulation for his turn. Anakin literally only turned to save his wife. Nothing to do with the Jedi.
“Some of the people had a hard time with the reason that Anakin goes bad… They didn’t seem to understand the fact that Anakin is simply greedy. There is no revenge. The revenge of the Sith is Palpatine. It doesn’t have much to do with Darth Vader; he’s a pawn in the whole scheme.”
-George Lucas, The Making of Revenge of the SithAnd that’s kinda hard for a lot of people to accept. So I think emphasizing more that Anakin’s only goal isn’t to prevent Padme’s death, but also his own and bringing order to the galaxy, bending the natural cycle of life and the state of the galaxy to his will, would be a good way to make his turn more layered.
He doesn’t specifically want revenge on the Jedi, but I think he does get angry with them. His frustrations with the council make it easier for Palpatine to sway him and get him to accept moral relativism. I did like that it wasn’t so simplistic as him just hating the Jedi.
Touching on the greed thing, I think one part people tend to miss is that Anakin could have left the Jedi if he really wanted to be with Padme. He loved her but he also had an ambitious side that wouldn’t let him pass up chances to advance and increase in power. “I want more, and I know I shouldn’t.” He wanted to have his cake and eat it too. Notice that’s how Palpatine tempts him with both things at once - he can save Padme by becoming more powerful. It appeals to his love for her and his ambition at the same time, and he gets swept up in it until his ambition lets the dark side overwhelm him and he’s force choking the person he’s ostensibly trying to save.
