I agree that all animals - all living things - deserve the same respect. No animal should have to suffer for a long time only because we humans can't be bothered to kill them quickly. It's true that in the meat industry, fur trade and other industries where animals are raised just for profit, they also suffer painful deaths because of human ignorance or lack of compassion. I'm vegetarian, but I could live with a company that killed animals if they had strict rules about humane slaughter (as painless as possible) and also rules about letting the animals live as natural a life as possible before being killed.
Ideally though, people wouldn't want to eat other beings. I believe in karma, even though I'm a westerner, and I'm sure there's bad karma being created where killing and using living things for profit is concerned.
