Throughout galactic history, there have been conflicts between Jedi and Sith. Despite their apparent differences, they seem perpetually united in their desire to destroy each other without hesitation.

Acts such as killing Sith just because they are Sith go against true Jedi teachings, which is why they are hypocrites. The Sith never compromise their beliefs in times of war or strife; in fact it is during those times that their beliefs are strongest.

That is not to say there are flaws to be found among the Sith. While the Jedi flaws are rooted in hypocrisy, dogma, and indecisive inaction, the Sith flaws are rooted in the flaws of those who become Sith.

A person who is weak and greedy, who will slaughter innocents for power, will remain that way after becoming Sith. Look at Palpatine. But a person who is filled with compassion, a sense of justice and order, and a willingness to be ruthless enough to make sacrifices of a few to save many, will carry those traits with them when they become Sith.

Anakin was corrupted not by the Dark Side or by Sith teachings, but by the self-serving lies and machinations of Palpatine. A man corrupted Anakin, not a philosophy or aspect of the Force. But Anakin was not truly evil, and the good he held before his corruption remained, and in the end, he proved to be the ultimate Sith and the ultimate Jedi at the same time.

Anakin was willing to take a life to save many. Anakin was willing to sacrifice himself to save many. But most off all, he was willing to kill one evil man to save one good man, his son.

Some might say, "Who is to judge who is good and evil? Who can be trusted with that power?" One who is incorruptible, one who is willing to put others before himself, that's who. Luke makes those types of judgments every day, yet he fails to act quickly enough which causes unneeded death and suffering.

Yet Luke should be commended for taking the Order in a new direction, for the ultimate path of a true Jedi and a true Sith intersect at some point. When a Jedi lets go of inaction and hypocrisy, and when a Sith is free of greed and selfishness, the two meet in a common goal to save lives.

The problem is that few Jedi or Sith grasp this; they are both blinded to the truth. There is a chance that Jacen will grasp this, yet there is a chance he will be lost to blindness.

The cornerstone of being a true Sith is the use of your inner strength, your passions and energy, out of a desire to create order. The Jedi do much the same thing, the only difference being they delude themselves into thinking they do not.

A true Sith would be willing to slaughter a city of millions to stop a war that would engulf billions.

A true Sith would be willing to commit genocide against an aggressor that attempts genocide against the galaxy at large.

Is there a grey area of what constitutes a necessary sacrifice from an unecessary taking of lives? Always. But there are no evil Sith or good Jedi, there are only good and evil people who happen to be a Sith or Jedi.

Above all, there is one defining question that makes one a truth Sith:
Which do you love more, the power you wield or that which that power defends?

If you know the answer, you are on your way to the path of a true Sith...
