At second 9 into the video, you can see people on top of the cliff. The man seems to not to be afraid of the wave but runs back to meet it. Why does he seem so unafraid of the wave? Why does he seem so joyful? My philosophy is this. He was experiencing the joy the devil was feeling watching the man be stupid. In other words the devil's joy of watching the man be stupid was what the man was feeling on top of the cliff.
