What's the best way to turn a Jedi to the Dark Side?

There's this cute Jedi chick snooping around on Nar Shaddaa.

Gonna go for it.

Slowly. If this is a play to get a date for the Life Day party this weekend, you might as well quit now or the Jedi might well cut your hand off. And then you'd have no date at all.

Unless a person desires the darkness, it must be brought up gradually, almost to the point that no perceptible change is occurring. Darth Sidious' tempting of Anikin Skywalker took years, and I'd argue that it was rushed. If Skywalker had been even slightly more critical or if his Masters had been more helpful, he might not have turned at all. To Sidious' credit, external factors pressed his hand and it did work out. 

To make a long story short, you have to figure out what she values most in the galaxy, then slowly threaten it (without getting caught, mind you). If she values peace, make war. If she values freedom, introduce tyranny. If she values her friends, endanger them. But *slowly*. You want her to feel anxious and worried, not completely powerless. Not yet.

Next, you'll need to increase how much power (e.g. influence, rank, status) she has, either by urging her to take it or by manipulating the situation so she is given some. Show her how her (slightly) increased power can help fix what is wrong. She'll start off using the power with the best of intentions, and will probably do a lot of good.

At that point, start tightening the screws. Make her start to grab for power. She'll still say it is order to serve the Light, and she may even be right. But enough power, taken quickly enough...it will lead to her downfall. Put obstacles in her way. Force her to make the tough choices for the greater good. In time, she like thousands before her will fall. 

In the end, she will cast off the restrictions of the Jedi Order and do whatever she needs to do in order to meet her goals. Only then will she be free.

Good luck!
