Umm, and what about the people who actually flicked the switch? No doubt the artist and the curator are culpable, but... that's just messed up.
It reaffirms the conclusion that when it takes two or more people to make a fatal decision, each will always assume that they're absolved from responsibility because someone else was involved. Like that experiment where one person was instructing another via a radio link to do bad things, and both parties assumed that the other was the guilty party because (he gave the orders/he did the deeds).
Or that experiment with the people off the street administering 'nearly lethal' electric shocks to complete strangers because someone in a lab coat told them to. Thus demonstrating that yes, Veronica, the Holocaust could happen again, anywhere, anytime. whoops
Ahh, Milgram's experiment strikes again.
I love that idea. But only two people pressed it?
