On the other hand, why would he care if it was easier for them to assume power if he was already dead? It's not easier to kill him, just if Vader did, well, that was how it would be. I don't think Palpatine started thinking about ruling forever until he saw Vader was no longer the ultra-Sith Palpatine intended for him to be.
