Yes, I think the problem is that people are mislead and/or misguided quite often.
Forget about the death part for a moment, and consider two people. Ali from Palestine, and Bob from Kansas.
Ali sees his cousin’s village crushed by tanks, and sees his friends roughed up now and then by the IDF. Heck, he might even see friends or relatives killed by the IDF. Or perhaps he merely hears talk of such things from friends. Maybe his government tells him the IDF sponsors terrorism against Palestinians, is preparing to use biological weapons against them, et cetera. The voices he hears from various sources tell him he is right to attack “them”. His intent is to get out there with a loaded gun and kill some people.
Bob watches the news. His government tells him the Middle East is a war zone. He is told there are people there who develop, buy, sell, and use biological weapons. He sees explosions, tanks, gunfire. The voices he hears from various sources tell him he is right to attack “them”. His intent is to get out there with a loaded plane and bomb some people.
One of them expects that he very well may die. The other does not. However, their intent toward their fellow humans is basically the same. They want to kill the bad guys, for the sake of those they consider the good guys. One of them, untrained and not too well versed in either tactics or any laws of war, maybe even with limited access to information and a skewed view of “the bad guys”, may pick a cafe or bus and blow up some dozen or so civilians. One of them, possibly educated, schooled somewhat in tactics and the laws of war, may drop a bomb or two on an air-raid shelter (as in Desert Storm) and kill 400 innocent people.
Intent? Big deal. Who cares? Either way, people die. People are told things, people believe things, and in the end people die.
Those deaths should be avoided. I believe the Koran says that the least harm we do to any person, we do to all of humanity. When possible, such harm is to be avoided. How can it be avoided? Stop listening to governments! Governments do not exist to serve us with pure altruism. They are not staffed by infallible robots. Governments consist of weak, greedy individuals, who work for their own benefit.
