[WH40k] Would it have been better to simply let the emperor die and then try to reform the Empire before it had withered for so long?

Would it had been better to simply let the Emperor die and then have the Ultramarines attempt to re-constitute the Imperial remnants (Sans Tera which would be overrun with demons) when the Ultramarines were at their strongest, instead of the current state where the Emperor will eventually die and the Empire and almost all space marine chapters are both withered and beset by enemies on all sides.

No. The emperor is the most powerful psycher in all of mankind's history. Without his influence and protection over us, there would be nothing holding back the terrible wrath of the daemon gods of chaos. Wrap travel would be impossible without his psychic divinity, and his death would instantly strand countless billions in remote corners of the universe, condemned to die at the hands of whatever beasts they come across.

Every day, a thousand souls are sacrificed that the emperor may continue to live. It would be worth it if it were a million souls being offered up daily for our god. Without him, we are lost, and the scourge before us would overwhelm us.

The emperor is no mere man. His psychic abilities are so powerful, they rival and even surpass that of the gods. Our survival is dependent on that; it is his blessing that protects us from daemons; it is his power that holds the daemon gods at bay. If he is ever lost, we are lost.
