To protect,a person is sometimes forced to kill.It is either that or die,or,watch somebody else die.Which way would you want it?Unfortuately the best money maker in the world is finding the fastest way to kill eachother.Just ask any high level person how profitable war is.(especially those that have large amounts of holdings in defense companies)
The premise of your question or statement is flawed to begin with as the picture shows a range used for both and others.
Does that picture scare you? Just asking.
