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.

Hahaha, thank you. But first off allow me to disperse your thoughts that I am some kind of neophyte, I will not waste my time trying to prove to you that I'm not because honestly I have nothing to prove. I wrote this not to ask HOW to but to see if any of you think it was possible, and if you had any theories on it. I do not take being called a young neophyte kindly so I ask in the future you use some discretion before making assumptions. Now if any of you read this please reply in the way I have asked, I hope I have made this perfectly clear.
