Your not really polarized as a "darkworker" unless your killing people, if not literally than in spirit, in my opinion.
Theres no real advantage to being a "darkworker" if you want to gain influence in the world. Unless of course you make the descision that you don't care if you crush people along the way. True darkworkers are mobsters, drug dealers, corporate ladder climbers unafraid to sabotage people on the same team for their own advancement, corrupt politicians willing to help pass laws they know will hurt or possibly kill millions of people. You can gain significant power from doing these things.
Please don't go out and murder someone okay? But think about it, it's not hard to murder a person and get away with it. If your really a "true darkworker" then you should make sure your parents have tons of life insurance and then find a way to kill them and collect. Wouldn't be hard. How's that sit in your stomach?
If your a darkworker you should have no problem stabbing people in the back. They don't matter. If they stop becoming useful or pleasurable for you find a way to extort as much benefit from them as possible and then you can start to use them by preying on their vulnurabilities and insecurities. You just have to learn to be slick and you can make many weak people think your their friend and give you everything they have while you laugh at them.
How fun. If your sick and corrupt. Darkworking is about as good a path as going to the darkside was a good descision for anakin skywalker in star wars. "Release your anger! Follow your dark emotions! You'll know the secret to immortality and have ultimate power!"
As the star wars movies proved
not only is darkness weaker, but eventually you cease to be a person at all and become more of a monster incapable of pleasure (from anything other than something maniacal) or normal human emotion, and constantly calculating some dark plot to gain power.
