I ran over a dog once and felt nothing for the dog. The owner was devastated, however. It was as if she had lost her husband. I did feel bad for her - I felt REALLY bad for her. I didn't do it on purpose, but I still felt bad. But ALL of my bad feelings were for the HUMAN owner, not the soulless walking meat. The phrase "ran over" is normally associated with driving, not walking.
walking was referring to the animal he ran over.
