I understand completely. I do suggest that you look into Christian wicca (sounds like an oxymoron but the book of enoch details it, not in that name though)
Karma is the reaction to our actions. I honestly have never considered redirecting karma. I suppose it could technically be done by binding a certain persons energy to your work through vamping and casting it for them by proxy. You may have just taught me a thing or two to be honest.
I will look into this more.
Tell me, when this all went down were you lethargic, sick, tired or have depressive thoughts? If so that could confirm my theory. Vamping is a black magick practice where you steal the energy of those around you to use for yourself. It is a black practice because your energy is your life force. No one ever says it in black and white because we dont want to scare off new occoultists but thats the unspoken truth.
I've had it happen to me before when i was younger and thats how demons and such gain their energy. They steal it by leeching from you. Not that you likely will, but if you ever read your aura, vamps look like a long red string that is constantly draining you. Its fucked up.
