I think some people are just "unbalanced" but I think many others have just been taught (brainwashed) that it's ok. Think about the people who club baby seals. Or, what about people who hunt deer. There are thousands of them in the U.S. Have you ever seen a deer up close? They really are beautiful animals with big dark eyes and long eyelashes. Really sweet looking actually. Yet people have no problem putting a bullet in them. Why? Because they've been taught that it's ok.
