It seems as though every evil known to man can be traced to that single event. But then again I am not qualified to post on this thread, as I have no post baccalaureate education. Are the kittys sleeping in the windowsill?
Well, in principle it’s a simple thing. Good and evil were things too large to fit into any human’s mind. As long as humans let God tell them what was good or evil as they came across it, they were safe. Once they began to try to figure that out alone, bzzt tilt, the problem will not fit on the hardware.
