It is not for me, a mermaid, to understand human minds. Were those who ran the Deepwater Horizon lazy, stupid, or greedy? I do not know. But I do know that equipment that should be inspected every 3 to 5 years had not been inspected for 10 years. Men did not know which lifeboat was theirs in case of emergency. Those who worked on the rig reported seeing unsafe conditions frequently. The mayday call was sent too late. The well failed a safety test, but was reported to have passed it. So do not think for a minute that this was a natural disaster, or an act of a vengeful god.
The act of a god came later, when King Poseidon, lord of the sea and its inhabitants, shifted currents away from sure, protecting the hard working fishermen who have nothing but love and respect for the ocean. The warmth of the waters encouraged the oil to break down.
