Have you ever heard the stories of what goes on in poultry farms? The same kind of people (ie. those with a thug mentality) work there, only instead of beating up old people, they beat up chickens. But it’s the same concept of choosing a job where you can pick on those who won’t fight back.
I think at the end of the day, we’re being punished for playing God. You say “Oh well, euthanizing the old is doing that.” It is, but so is trying to prolong a family member’s life at all costs without accepting that everyone has to die sometime. It works both ways. We want Grandma to be with us forever, but in our efforts to do so, we often just end up making her suffer more.
The long and short of it is that bumping off people and trying in vain to cheat death (everyone’s eventual fate) are both playing God in different ways, and they always end badly.
I once saw a worker at a veterinarian kick a dog as I drove by. I called and reported him to the veterinarian. People are supposed to regard other living things with respect and care. Yeah, it takes patience and big deal they are irritating and cranky. BUT THE WORLD IS NOT REVOLVING AROUND THEM AND THEIR PEA BRAINS.
God is watching.
