"I believe it is possible to kill with compassion and in a non-violent way. An example would be a police officer that does so to protect another's life. Does this meet the definition of violence?" Kevin Leavitt
This does get tricky doesn't it? Compassion for the attacker or the people affected?
I agree with you, John, that Kevin's example is not exactly what I'd call killing with compassion. I'd agree, with Kevin, though, that such a thing can exist. I've seen plenty of compassion in people who decided they needed to put their dog down. I think that there is real danger in legalizing euthanasia, but I also think there are many examples where the overwhelming emotion is, in fact, compassion.
This doesn't lessen the issue of karmic consequences. It just complicates it.
