I would suggest the compass was an illusion created by men who had no scientific understanding. Ill use two examples.
1) Thoughts of a sexual nature are regarded as unclean and forbidden. But we are not the masters of these impulses, our hormones are. We can at best only control the outcome of these impulses. If these impulses are evil, why do we get them and get them often? If there's a God who designed us, this would suggest there is a major design flaw.
2) Much of the behaviour (eg. Suicidal tendencies, addictions) deemed as demonic we know today as being the result of chemical imbalances and various other biological elements in the equation and not some paranormal force. Again if we insist on hanging onto this belief system we suggest a design flaw when He's supposed to be perfect and all powerful.
I don't suggest I'm in the right here, merely that this is my view with the issue of judging human behavior with biblical principle.
