There is no Sith Empire. It collapsed all by itself, with no help from you. More to the point, I could provide plenty of evidence, but past history has proven it to be wasted upon you, Trent. Your perspective on the Jedi is singular, and certainly not one you perceive flaws in. Anyone's attempt to present evidence to the contrary would be rebuffed, whether logically or from sheer belligerent posting, to the tune of "you're wrong, because you've not convinced me otherwise". Difficult to do, when you're not listening.
The real truth? The Jedi ideals were always irrelevant, provided that there's an evil enemy to destroy. The notion of peace exists only provided there's nobody standing in the way of the Jedi's perception of it. Enter the Sith, or any other 'evil' power, and the Jedi mobilise (aggressively, as soldiers and warriors) to attack and destroy it. Not seek diplomatic solutions to create the peace, nor work within the boundaries of afflicted worlds to relieve suffering or protect their populations. The inevitable consequence is far more base: see a Sith? Kill them. Thus do we pacify the Galaxy.
It's all very amusing, really. Most especially when it's aggression wrapped up in espoused moral dogma.
