Void between "Bad" and "Good" magic traditions Options

[Machiavelli]

Actually i read the topic about the blood mages and the bounty that is set on a verified blood-mage. This brought back the question to me, where exactly you can draw the line between these two sides of the force. Practically everybody can learn the blood-magic rituals, no matter of his tradition and i admit that the benefits are good, but it is nothing they deserve to be hunted down more than every other shadowrunner. Ok, usually you kill people in self-defense or because you have a corresponding job, but death is death so why is there this extraorbitant bounty? Black mages do everything for their personal power, they deal with every kind of dark spirit to enhance their abilities and this entities also include e.g. draining of essence, karma and the like. Voodoo priests raise the dead and i haven´´t heard about a bounty on neither of these groups. Maybe i am too apathetic to see a problem here, but except that they kill people to reach their goals, i see no reason for that head-money.
