It’s like that psychology experiment years ago that went something like this: they recruited random Americans to assist by hitting the shock button/lever whenever a guy in a lab coat told them the “test subject” gave an incorrect answer. Most of those recruited willingly zapped the actor who gave the wrong answers because their submission to authority figures [in lab coats therefore “experts”] was so strong. Very few refused to participate in torturing a fellow citizen.
If I knew it was an actor, I’d zap the actor! It’s not like they’re human or warm & cuddly like a dog or cat.
