"Killing is good whenever we're the ones doing it, and it is bad whenever it is the other side doing it."
So says bin Laden, Bush1, Mullah Omar, Hitler, Popes and Kings who ordered the Crusades, Stalin, Bush2, and various other bloodthirsty tyrants.Killing is never good. It is done, often by people who convince themselves that it needs to be done. However, it is never a good act.
You say it is good because it is our side doing the killing on an enemy you have been told deserves it. ... "They" do the killing to an enemy they have been told deserves it. To them it is good, just as much to you it is good now that our side kills.
A video of some people (for the convienence of reference, lets call them Palestinians) who you are told are cheering about the WTC being attacked, is bad. A stadium full of Americans at Yankee stadium cheering at being told that our bombing has begun, is good?
There exists no difference between the two sides, if that is the best argument you can produce.
