Your story of the frog reminds me of a time I shot a squirrel as a kid. I had been taught that red squirrels were the enemy, but I accidentally killed a fox squirrel. It was such a soul-crushing experience, the pain was unpalatable, and I suffered throughout the night trying to justify the action, somehow trying to convince myself that it was a good thing. I settled on the justification of making my war veteran grandfather proud. This article is good, it raises a lot of important questions, but doesn’t pretend to have the answers.
