Do you think people can eat meat from other sources and not be considered psychopaths?
If someone wants to start a puppy farm for the intent purpose of eating them, fine with me. My guess is that in this country it would be a horrid business model and I would use my resources to boycott them and try to put them out of business.
If wild puppies existed and someone went to hunt them, fine with me.
And heck, even though I hesitate to say "fine with me" on this following one, if some sick **** wants to adopt a puppy for the sole purpose of eating it, even that doesn't cross the line this guy did. This guy had children who grew up with the pet and decided to eat it. Father of the ****ing Year material right there. This guy did not do this for food. He did it either because he's completely mentally insane, or because his children did something he disapproved of and he wanted to punish them for it by mentally scaring them for life. Either way **** him.
Considering I eat meat every day from other sources, I would say yes to your question. But I am sane enough to not eat my pets. To use a pretty classic example, it's one thing to buy a rabbit to raise as food, another to buy it as a pet and then decide "well **** it, I'm going to kill it now and eat it." The latter suggests a highly unstable mind.
