To tell the truth, I was thinking of posting this a long time ago. The little exchange you mention just brought it to the fore.
Jiva daya - “Jiva” meaning “living soul”, and “daya” meaning “kindness” - is the ground of religion, according to Hindu dharma. But it is interesting to note this verse from one of the Puranas, this is memory, not word for word:
“Even saints are happy when poisonous creatures like vipers and scorpions are killed.”
This was in reference to a powerful and evil tyrant king being killed. So even peaceful kind humans are wise, and know that violence sometimes must be meted out to those who are not peaceful, kind or wise.
First on my list of those still living, would be the cabal which speculated that at least 25 million Americans would need to be 'eliminated' if they refused to accept the 'revolution'.
