I remember the basic D&D write-up of imps stated they needed seven souls in order to become a full demon/devil (pretty much the same thing under that system).
I figure it this way: if the imp is constantly trying to get it's master's soul, no one would get them as familiars. So you use the familiar bond as an excuse to come to the Prime, and then go after other people's souls. If you get in trouble, you rely on your master and is clueless do-gooder friends to protect you. And, if you do it right, that seventh soul you take is your wizard friend's.
