The rule of two for the Sith does kinda make sense.


Over a 1000 years ago, there were thousands of Sith, under the leadership of Lord Kaan (Legends). They basically fought the Jedi Order to a standstill, but were eventually destroyed as the Sith in their nature crave power so they turn against each other.



Bane realized two things.


1) Sith can't work together in the long term, and an army of Sith is never going to defeat an army of Jedi.

2) The more you spread the force out, the more you weaken the individual, he saw the force as a finite pool basically. The fewer the Sith, the more powerful the individual.


So he reformed the Sith Order (Ie killed off all the Sith but himself).



In the rule of two, he felt that he was creating two indivduals of supreme power to the individual jedi. The Sith Lord had all the power and knowledge, his job was to teach the apprentice what he knew, the apprentice had the obligtion to learn from his master and learn on his or her own. Thus eventually surpassing the master.



Bane also theorized that a Master that took on more then one apprentice was a fool, as the apprentices would eventually team up to kill the master.



At the same time, Bane realized that the Sith were never going to defeate the Jedi Army on Army. So he created the Grand Plan, which was to work in the shadows, use cunning and deception, and slowly corrupt the Republic, so Bane built networks of power brokers, and information brokers and corrupted senators, and his apprentices carried on that work right up until Palpatine. By the time Palpatine took power as the Supreme Chancellor the Republic had rotted. But the Clone Wars and putting the Jedi in the position to be slaughtered by their loyal clone troopers, that idea was all Palpatine.


So the question is, what happens if the Lord of the Sith is killed before his apprentice can learn all he can learn. Well, the Sith Order suffers a blow but its not crippling, as the apprentice becomes the Master and the Force will provide an opportunity for an apprentice. If the apprentice is killed, like Maul was, the same thing, The Sith Master retreats, finds a apprentice and continues on.


If both are killed, then the order ends, so you rarely see the Master and Apprentice in vulnerable positions together.
