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.

if 'soul' defined here is purpose(idea) or energy that carries purpose of individual, 'entity' inside us with karma program, and stealing would be deprograming that entity, changing path of individual by changing 'purpose'.
it could be , it is really (self)destructive action to do playing with someones karma, it would be less painful i believe if subjects are willing, but it ends all to one thing- i believe that one manipulating other ppl souls is taking 'karmic responsibility' for them.
and there are more simpler ways to do that purpose transfer than triangle&barbaric names
