Did Sideous Break the Rule of Two? And did that lead to his downfall

Recently finished listening to the Darth Bane Books. Established the rule of two One To embody the power of the dark side and one to crave it. Now I’m not asking about having multiple pupils. Even Bane took on a second when he feared Zaia had failed him. My problem is the way palp beat his master. The entire point of the rule of two was to cut out infighting and betrayal of the old ways and to fight the double eged sword that is the dark side. To have two siths and only the most worthy of the mantle the balance of the force will insure that each generation is stronger than the last and that the pupil is either to surpass the master or fail in their challenge and the master will find someone worthy of the mantle. But by killing his master in his sleep instead of openly challenging him. He’s betraying that logic and reverting to the old ways that bane cast aside. Which in turn made for a weaker line. Maul wasn’t worthy Doku wasn’t worthy then when Darth Vader rose to power he did have the potential to surpass his master but palp did everything he could to weaken his pupil. Bane has a chance to do that with his but he taught her Sith sorcery the very thing that led to his downfall. The sith to this day are basically over because Palp was selfish and ruined his order by putting himself before the Sith. What’s your take on this entire thing? Is the rule of two a mistake? If Palp would of followed it closer and from the start helped Darth Vader be as strong as he could be how would you see the story ending up? via /r/StarWars https://ift.tt/z0YlwOC
