I agree it was ridiculous, but why would the woman validate the question by giving the most obviously abhorrent response? That just made the question no longer ridiculous, because she answered in the affirmative.
In other words, "can a mother murder her toddler?" is only a ridiculous question if everyone in the room agrees on the obvious answer. This time, not everyone did... somehow.
I think it's alarming that we can't be sure whether this woman was doing that or not. Her skills are one-point if it was just an act.
