Are there any gray jedi who left the order to become petty criminals?

Are there any rogue jedi who left the order to abuse their powers for evil? Not Palpatine evil, but like petty crime evil. Maybe even to the level of Maul trying to take control of pirate activities.

hmm, didn't a'sharad hett become a bounty hunter pre-Krayt? iirc

Well I guess Ventress and Aura Sing count, but I was thinking along the lines of purse snatchers, muggings, etc. Real dirty work where they abuse the force.

Set harth, though he seemed like more of an up scale criminal.
