[Star Wars] What was the point of Operation Cinder? (spoilers)

>Operation: Cinder was carried out by the Galactic Empire as a means of devastating several Imperial planets in 4 ABY, only a few weeks following the Battle of Endor. The operation was part of the Contingency, a plan devised by Emperor Palpatine to ensure that the Empire and its enemies did not outlive him should he ever perish. The plan was put into action following the Emperor's death during the Battle of Endor. 

I'm not exactly sure, but I'm pretty sure there's a line in ROS where Palpatine mentions that he's died before and that resurrection is nothing new to him. So what was the point of torpedoing his empire? Why not just have the plan be "hey guys if I die just pick my body up on the sith planet and plug some tubes into me"?

It was a culling. As far as Palpatine was concerned, the main purpose of an empire is to protect its emperor. It had failed to do that which meant it had grown too big and was inefficient. So his plan was to basically wipe out most of it except for the select few he hand picked. And in doing so he would also wipe out most of the New Republic so the select few he picked to become the first order could go in and fill the power vacuum when they were ready. 

The wiping out the New Republic thing didn’t work out when they failed to blow up Jakku, but it did trim down the fat of the empire and let them go off to rebuild in secret.
