I have had an unexpected change of heart, and more precisely, an unexpected moment of clarity.
For a while, I have viewed our species' impending demise as both an outcome of our collective cruelty and inability live in peace and cooperation, and as a kind of accidental vengeance we bring upon ourselves.
But it has occurred to me that this will be a kind of mercy killing by the universe.
After we have gone, we will no longer suffer from the misery brought on by our own collective cruelty.
