I recently shot a raccoon with my bow.
This is something rare for me: I don't kill wasps, mosquitoes, anything.
But this was an insane raccoon, and posed a danger to me, my wife, cats, rabbits, other raccoons...
It had to go.
So, responsible people do what they have to, even if they hate doing it.
This is probably quite different, though, to being emotionally motivated.
