The exact point at which something becomes "evil" or "villainous" is quite hard to define. There's generally a feeling, however. It's the point at which an otherwise innocent person no longer feels safe, the point at which a line is crossed and trust is no longer possible. And that line is crossed in many ways, from many angles - from the sides, diagonally, top, left, bottom, you name it. Every line is a little different.
