Truly a hardy foe! One question: how evil is obviously evil? Are we talking 'steals for the fun of it' evil or ' addicted to whorehouses and decadence' evil or only really 'rapes child slaves on a regular basis' evil?

God, what a horrible analogy...

I'd say someone with truly evil intent in their heart. Now, I know that sounds pretty vague so allow me to elaborate. It'd be someone who is well aware that whatever he or she is doing is truly evil. However, petty sins wouldn't be counted, otherwise the damned thing would never stop vibrating. At any rate, it would detect the first and third one of your examples.
