Aren't there different types of Daemons? I don't know exactly how the daemon world works, but I thought lesser daemons like daemonettes, bloodletters, nurglings, horrors, etc... are different from other daemons as their will is bound by their gods and they pretty much are mindless and don't have a will of their own. Correct me if I'm wrong. And then we got other daemons that have either been changed to daemons or have been created in the warp by centuries of souls being absorbed by it.
