Vader vs. Sidious (Who was more important in the force)
After constant nagging and debates between TOR fans and people who constantly reiterate the same arguments for Sidious being the SUPREME Sith. I'm asking the fundamental question of who is more necessary to the Star wars Mythos. Vader was constructed by the force to offset the diabolical machinations of Plagueis/Sidious, but Sidious is the very reason why the Empire exists/and truthfully wasn't even bothered that much that he reappeared in DE? But as a two-pronged question, what character is more essential to the SW mythos as a whole?
