Many if not all of us would be okay. Not to mention that many people have some experience of killing animals for food anyway.
My philosophy is that I only eat meat I would personally be able to kill, which means chicken, ducks and fishes (probably game too). I still avoid battery chicken though.
I’ve worked on a slaughter floor before, and while it’s certainly not an enjoyable experience I can say with all honesty that a great deal is done to minimize suffering.
