There are many things people could cite as differences between mankind and animals. The biggest difference could be summed up in one word.
Man has at least one characteristic for which there is no parallel in the animal kingdom.
Animals do not possess a conscience. The conscience is a God-given measuring device by which a man can determine whether his behavior is good or bad. A sociopath or a psychopath is one who is said to be without a conscience. Every human being, regardless of origin, race, creed, or color has a conscience. It is given to every child at birth.
