I hope to expand on this spiritual problem, which I have called by different names. Basically these people are hard hearted like Pharaoh in the Old Testament. They have no empathy for anyone and use everyone for their own ends, whatever that may be. And when they are through with you, they will happily throw you away. With one such person I noted to them that I felt like I was a necessary evil. When I was no longer necessary, all that was left was evil, and thus they threw me away. These people can be persuasive. However, when you cross them, and you will, you feel like you have been dealing with a porcupine. I am still pulling the quills out from the various people I have dealt with.
