I cannot find any link right now, but I remember reading about the Milgram's experiment, or one of it replication, and one of the test was with and without glass, what looked like a more direct connection between the button and the victim or via a machine, etc... and that one of the conclusion was that the more indirect connection, the more distance, the more elements between the person pressing the button and the victim, and the more likely the person was going to push the button. By the way, have you ever wonder which type of meat you would eat if you had to kill the animals yourself?
