I know Mr Tumnus wasnt all bad, but I distincly remember thinking as a child, you didnt HAVE to betray the children now, did you! And I could never work out if he was fundamentally good, or evil.
My boss is just like him and I cant help thinking... Hmmm... are you good? Or bad? Can I trust you? Or not? [eyes narrow insuspicion]
Hes a bit shifty anyway. Perhaps its that!
