Humans are Inhumane.

Human vanity has led us believe, that when one person kills another, it is something alien to our nature. We have therefore coined the word "Inhumane" to suggest that this unpleasant act, is but a social aberration.
However, when we scan the history of mankind from the earliest known beginnings until today,
we can see clearly, that humans have always killed one another in large numbers; and that they continue to do so.
It would appear that is actually inhumane not to kill other people. The dictionary reference should be amended.
