This is a ridiculous notion.
Should anyone that can't write code not deserve to use a computer? Anyone that didn't go to med school not deserve to get medical care? Anyone who can't rebuild a motor doesn't deserve to drive?
I am not saying that people should have to kill everything they eat. I am saying that people should all know that when they eat meat, they are indirectly killing an animal so why shouldn't they experience a direct killing? There is nothing wrong with indirectly killing it but I wish people were closer to reality.
All those examples you provided are of non-living objects and aren't an effective parallel.
The point was "life and death". If one can't accept killing then they shouldn't eat meat. Likewise, if one can't cull animals at death's door, they shouldn't have animals.
I hope that doesn't sound ridiculous to you.
