You missunderstood. I was using the term and the other references with some irony. I suppose there might be rare occassion when a killing IS compassionate .. a) when I shot my 17 year old dog through the head rather than leave her wreaked with cancer and suffering horribly in her last days - not even being able to stand up. b) a relative of mine was involved in a horrible car accident a few years ago. He was basically burnt inside and out. Failure of most of his organs - except the heart. No skin left to 90% of his body. He was on a machine for a week. There was a choice to keep him going with little hope of ever living anything remotely resembling a normal life, or not. His wife and kids chose not. Out of pure compassion. Other than incidents like these, I can't see it.
