> "Imaging-wise, pig hearts aren't too different from humans. Plus, we can give them a heart attack in the scanner and not go to jail. Some labs use dogs. I just can't do that."
I wonder if they'd feel differently if they thought about how pigs are more intelligent than dogs.
Basically all of society is about conveniently ignoring ethics in illogical ways because it provides immense inconvenience and reward. I'm sure they could convince themselves that giving a pig a heart attack is just as evil as giving one to a dog, but then they wouldn't be able to perform studies which will save millions of lives in the future.
