A Single Religious Command from the Pope Killed 50% of Europeans

A dangerous rat that is about to attack an innocent piece of pasta

Rats are the most adorable, most misunderstood animal on the planet. They are highly intelligent, and will even refuse to accept food - which they love - when they discover it will cause pain to other rats, a previous study showed.

Statistically 1 out of every 100 people is a sociopath. The latter lacks the physical ability in their brain to feel empathy for anyone and anything but themselves. Though no fault of their own, they can watch other humans and animals in pain and enjoy the sight of it without offering any help or showing any compassion. They can rightly be called inferior humans.

  Here in our modern day and age, with the most information available in the history of mankind at our fingertips, people still kill rats because of ignorance, and.... yes, religion.

Back in the Middle Ages (when religion ruled, and scientists and intellectuals were burned alive) a particular pope hated cats so much, that he ordered all cats to be killed. (I forgot the particular legalized con artist's name, so Google it. Pope Gregory or Pope Poes or something.)
