Nope. That was the whole point of having force ghosts as a plot point. Anakin fell to the dark side to try and save Padme and live his ideal life but the tools he needed to save her and cheat death were only possible through the light side all along.
Palpatine or more correctly, Darth Sidious, lied. The dark side itself has no means of living forever in the force or healing someone using the force. Those are fundamentally light side abilities which is why they perpetually eluded the Sith. It’s the reason why Sidious had to turn to bioengineering to find a way to make clones that retained his M counts and which he could transfer his consciousness into via the dark side.
I get the feeling that a lot of viewers miss the irony of that whole thing. If Anakin had been wiser or his teachers more empathetic and less dogmatic he would never have fell to the dark side and would not have been susceptible to Darth Sidious’s manipulation.
He’s a survivor.
What would you have done differently than him? Die?
