We could probably say that cutting someone's head off with a quick blow with a sharp sword is more "compassionate" than throwing someone into a river full of piranhas ...
But beyond that, killing is never compassionate.
What has that got to do with compassion?
If your head was to be cut off, or if you were to be thrown into a river full of piranhas, or were to be impaled or burnt at the stakes -- would you feel like you are the recipient of a compassionate act?
Would you thank your killers?
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.
