Stealing Souls, Satan can do it..can we? Options

I am curious, not because I am a satanist but because I really would want to do this. I always here of people (usually satanists) selling their souls or making a pact with a demon or something but is it possible for another human to infact give away their soul to another? My reasons for wanting to know your opinion are quite private but I just am wondering what you think.

That sounds very interesting...lol unfortunetly my magick is extremely casual so I dont know how well that would work for me. Me being a chaos sorcerer (or whatever you want to call it) my magick is quite on the spot, the rituals I do dont have any special formulas I just take what has worked for me in the past and apply it to whatever I might need. The only thing that remains constant is my prayer to my gods (Anubis,Osiris,Isis and Ra) who have been guiding me for more than a year but that is besides the point...
