Weird question! And without any analysis of the answers, an equally weird conclusion.
Logically, most people aren't going to choose "merely" teacher, as it's totally neutral when you have two such modifiers. If asked of me, I'd likely be thinking, "Hmm, a person whose deciding character trait is that he/she is a rapist is probably not out for chump change." That'd leave the last choice.
But then again, I'm probably thinking too much. (Thinking at all might be a drawback in the case of their respondants, I fear.)
Someone ask the perfesser if he'd like to test again and this time show:
Teacher
Atheist Teacher
Rapist Teacher
