[Star Wars] Why do the Sith have the rule of two? Wouldn’t they be much more powerful if they had dozens or hundreds in their ranks?

There used to be a Sith Empire, with acolytes and masters and everything in between. But they were constantly bickering and backstabbing, to the point where they spent almost as much of their resources fighting each other as they did the Jedi. 

Then Darth Bane came along. Long story short, he decided that the Sith order would be a lot more productive if there were fewer of them, so he killed all the rest. Whether or not he was right is irrelevant, because he had the power to enforce his beliefs.
