Overthinking "we don't know the circumstances" can often lead to paralysis and numbness. Despite humanities best efforts they can only deal with the facts and on this forum we can only work with what we know, true or otherwise.
So you don't like mass murder what would you prefer:
All alternatives to mass murder and applied to both the human race and the animal kingdom.
"Dobbed" in......seems to apply to killing a queen and seems to be seen as a necessary evil....I've never done it.
Killing one bee seems to be acceptable. Without any reproach from the forum, beekeepers regularly say that they have dispatched annoying "follower" bees.
Some people seem to care less than I do when crushing bees replacing boxes.
At what population number does it become sinful to kill bees? And does motive play no part in our judgement?
