Something people often overlook is that ******** get what they want. Be it right or wrong, it's effective.
Darkworkers are limited by one thing-cause and effect. If you can accept the consequences you can take any action. There's no mandate to adhere to conventional morals, to restrain yourself from harming anyone, or to "not be an *******" as some in this thread have stated. Liberty and pragmatism are the defining traits of the path.
Paradoxically, you need a strong code of honor. I've never seen a successful darkworker who doesn't have one. The thing is that it has no correlation to societal norms. It's okay to be an ******* so long as it's within the boundaries you've set. The only relevant question is, "who are you?" If you're the kind of person who does what you're doing then by all means continue.
I remember when I was asking myself, "Why are you a darkworker?" and I got an answer back, clear as day, "Because I want justice." I responded with, "What is justice?" and what I got was "Whatever makes me feel good." That, to me, is the essence of darkworking.
