“[Anakin] weighed Padmé’s life against the Jedi Order. It was no contest”. Matthew Stover’s Revenge of the Sith
Vader’s thoughts: Space Cult that constantly uses me as a sharp weapon but devalues and demonizes my humanity? Doesn’t trust me with anything? Tells me to rejoice at my wife’s death? Versus Sith master that has been an understanding mentor and offers a way to save my lovely wife? No contest at all.
Don’t forget that Anakin did asked for help from the Jedi, when he went to talk to Yoda and he basically got a “lol, just let that person die, there’s nothing you can do, stop being a bitch about it” and then Palpatine appears and tell him “Hey! There’s this thing that the Jedi don’t want you to know and it will help you save the ones you love, even save them from dying”
Anakin didn’t want power for him. He only wanted to save Padme and his baby
