Would it be ethical to read someone’s mind or is that the only true form of privacy?

Your mind is precious and personal your true gift of privacy that is protected. Not even the Devil can read your mind. But he is a good guess on what’s on your mind, he has thousands and thousands of years experience to guess the mind of men. When the Scriptures say men it means mankind men and women. However the Devil don’t have the power to read men mind.
