Ethical Real Life Games

Looking into ethical issues that have come up in game design I came across a real time game which uses bacteria and single cell organisms which can be influenced by electrical currents. 

Although not completely computer generated this brought up the interesting question of morals. I found that I was slightly repulsed by the idea of using charges to shock bacteria for our own amusement where as if its virtual I find myself indifferent to violence and other moral questions.
