Humankind developed from animals. Many people would like to claim otherwise, but wishing doesn't make it not so. Our past has left quite a few legacies in our minds and bodies. Most importantly, emotions. Emotions kept our animal ancestors alive and functional.
A common sci-fi trope is humans being replaced by robots. Robots would have minds like us, but would be mechanical-based, lacking the emotions that served our animal friends because it would serve them no purpose.
Together, I think this serves a good model of what humans as people are like. Emotional like animals, but also logical and abstract like robots. It would be wrong to remove either trait, as that would reduce us to the other one. A person with no emotions is a poorly made robot. A person with no thoughts is a crazy beast that must be confined to a cage for the good of the rest of us.
