It certainly is a horrible shame the way some people think these as well as pretty much all living things are put on Earth for man's fun, or satisfaction.
While God did give mankind permission to eat meat after the Flood of Noah's Day, he still required the animals be treated well, and even their death for food, should be out of necessity, not for "BUTCHERS."
About fifty years ago, my father was out of work, and it was difficult to get a job.
Even though he was an Electrician, and was accustomed to fairly good pay, when there was no work, he was not too proud to do whatever he felt was necessary to earn a living , and feed his family.
It happened that he knew a man who raised Turkeys for food, though in no way under the conditions we sii in the video you have up.
Still, he just couldn't take having to wade through blood, halfway up his boots. I think that is the only job, my dad just couldn't take.
He always took good care of any animals we had, even if we were raising them for food, at that time.
He did grow up on a farm, which gave him a different view of such things. It just never prepared him for a slaughter house.
Thanks to God's pland for the new Earth, we won't have to eat meat, and neither will the animals anymore. Isaiah 11:6-9
