They ask questions like...
"Why do people care if others' feelings get hurt?"
"Why do people feel excited for others?"
... among other dumbass questions that even a complete socio/psychopath at least INTELLECTUALLY, knows the answers to. Trying to make themselves out to be cool, profound, scary, alien & interesting, by pretending not to understand what you pretty much have no choice BUT to understand.

Then someone else who wants to look cool & alien comes along and provides a COMPLETELY WRONG answer that has nothing to do with empathy & everything to do with selfish gain; feigning their own lack of understanding.
Even for those of you who HAVE no empathy: YOU KNOW HOW IT WORKS! Stop trying to make yourself look MORE like a freak so we all think: "Wow. You must be so interesting since you're so different from us HUMANS that you don't even understand the basics." It's pathetic.
You'd be DEAD if you didn't know the answer to those questions.
