Well...You might go to hell!
no kidding, Hell is real, At least in my world. No! I'm no Christian and don't respect the almighty god at all. I think he is selfish, acts like a child and in general pretty fucked up. (there! Now I go to hell!) Here we had Aesir faith Before we where forced to be Christians. And those gods where actually grown ups up did something. (I don't follow that religion either)
Back to the topic, Bad thing will happen even if you don't use magic. Thats life. It's only that if you drive a car drunk before age 16 and without lifebelt, well...that might just end bad.
If you ask me what i Personally beleive I beleive black and white is just two labels. Words in mind and mouth. Nothing more. Nothing less (word is power). Maybe a way to keep covens from spiting up, I don't know? To me, magic is magic. White magic is as dangerous as black and can end as badly.
If white magic is to heal. Then think if one of the terrorist that flew one of the plane into world trade center was deadly sick (probably something like that or very poor) If someone healed him in good will, so that he later could take thousand of lives. The one who healed him actually killed thousand of humans just because she wanted to be good and heal the man that had it so hard. (Yes, even the terrorists is humans that lives very hard lives. It's all about politics and religion "which is politics"
Everything you do in life could end bad. If you want a safe life I suggest to follow the society. look around you, do and say as everyone else. Listen to the politics and make yourself beleive that what they say is true. that the world is simple and only one way is freedom and right.
Or you could take risks. Live the life, Coase in real life outside the politics, religions and even the law, are a very scary world with so much untested ground. Just trow yourself out there and se how long you can survive. Thats what life is about. surviving, feeling, experience. Not do the same job in 40 years and die of depression.
Well, to do all this in topic. The ones who call it black and white magic, that is the ones who control the mass. and the ones who just follow the lead.
The ones who lives there own lives. Listen to there own bodies and dreams. For us, there is only the truth. Our truth! And it's individual.
Is black magic dangerous for you? What is your truth?
