You are right, but I believe putting a cease to life is not inherently bad. If we could kill animals without letting them feel anything, that wouldn’t really be bad.
This is why we should be killing pigs with nitrogen, rather than CO2. CO2 is how a mammal determines it is suffocating, meanwhile the air is mostly made up of nitrogen so we ignore it. However, it’s precisely this which makes it dangerous to humans working nearby (also the fact that CO2 is heavier than air so you can have open pits), and it’s ruled too expensive to do it humanely.
We both know that’s not going to happen. If I want to have bacon, would you rather me quickly and painlessly kill the pig, or use a blunt butter knife to kill them?
I like bacon. Also there’s something to be said of the simple fact that almost all life eats other life. Why is plant life lesser than animal life to you?
However, the day they start selling lab grown bacon I will gladly switch to that.
Ethical consideration has to extend to more than just painless death to be worth a damn. I can’t walk into an infant ward and painlessly murder infants in their sleep for a reason.
