Yeah I mostly threw it out there because there seems to be a belief here that essence transfer must involve a defenseless person and anger/vengeance. But clearly that isn’t necessarily true, because Palpatine was able to do it with his clones as he died on the Death Star. Otherwise he wouldn’t still be alive. I don’t give a crap about the “all the Sith live in me” hand-waving. So there is more to the ability than what is shown in the film. That’s just my head canon on it all.
