If you knew how often your ancestors did those things, you would laugh yourself in the face.
Just about everything in the Occult has suffered the wrath of the Inversion Magick. You should know this, considering figures like Crowley did anything but hide this fact.
Figures like Marbas used to help us. They're delighted to assist us, but they always offer a deal and always have.
Should you choose to accept a poorly skewed deal, that's your fault. You made that bad choice. That doesn't make the dynamic "evil", it makes you, instead, look deluded. Of course, it's easier to prey on weaker beings, which is exactly what all of us are after suffering atrophy which impaired the abilities our ancestors long wielded throughout much of antiquity.
Pouting about how this makes those figures assholes is like a child refusing to play a game because the rules are unfair. Who do you expect to play with you if you act like this? Enjoy yourself playing, or simply find another game to play.
