I have killed so many live creatures in my professional,
however, I never intend to cause them unnecessary suffer.
Kill first, then cut.
And I refrain myself from eating anything considered cruelty
(from non-vegetarian's viewpoint), like foie gras, live seafood,
and endangered species.
That's what the Buddhists keep preaching,
I confess that I'm not vegetarian, and I've killed animals and fishes.
But I usually kill them quick before I proceed.........
