I've asked this before and have learned a lot just from more experienced practitioners like Noc and Lamp... here is an old summary from Lamp on positives:
Na'rayah, when you have the time, can you tell us a bit about #4? You mentioned that a demon can kill cancer cells. I find that fascinating.Lampropeltis wrote:Agreed, she was quite well-spoken.Terror Misu wrote:Interesting. I'm sure there are many many reasons for BA practice, including protection, and I'm open to hearing them so I can set aside my ignorant views and broaden my mind.
Noctem put it far more brilliantly than I did and as always, has my utmost respect.
As to your question, there are multiple ethical and constructive reasons to work with BA energy.
1. Janitorial services to fix things that other people have royally screwed up, be it throwing that ring in the volcano, cleaning up after hubristic dabblers, or binding/sending back to Hell highly destructive beings running amok that shouldn't be here in the first place.
2. Protection, ie, 'better the devil you know than the devil you don't' (though 99.99% of the population would be better off using WA/DA for that purpose)
3. A rare few have extraordinarily freakish wiring that allows them to actually prosper when working with BA energy, and acquire the dedication/knowledge to handle it responsibly and not allow it to explode in their (or anyone else's) faces. (the knowledge/dedication would hopefully be acquired well before) (and I do not believe the term 'extraordinarily freakish wiring' to be intolerant, merely a good description of an astonishingly unusual state of being.)
4. While not in itself Black Arts (due to its positive effect,) someone extraordinarily proficient and accurate in working with destructive forces, could aim them at say... a disease (without permitting that energy to affect the ill person) and thereby cure the patient.
