It always puts me off balance when Cowcar or Donut make a serious comment without twisting it into something odd.
I suppose an argument could be "how is it fair if the person doing the killing is safe in a bunker down the road from their home" but an argument along those lines would make attack helicopters and naval bombardments a bad thing, since they can engage targets from a distance that renders them invisible to the naked eye.
If anything drones are a good way of killing people. If the pilots find it easier to disconnect from the killing it would reduce the post traumatic stress. Why have more victims on the winning side than you have to?
The only problem I see is one that applies to any form of combat, correctly identifying targets. It happens to all levels of technological warfare, from sticks and stones to guided missiles, people make mistakes and kill innocent civilians after accidentally identifying them as an enemy.
When ending someone's life becomes non-traumatic or non-stressful I'd argue that humans are no longer fighting wars, but observing machines do the work for them. Part of the idea of having an army fight a war, and not a civilian population, would be that those individuals will endure the physical and psychological hardships for us, hence why it is very respectful to be a member of the armed forces of your country. These drones seperate the members of the armed forces from the technologically adept civilians who will operate them.
I'd also argue that equating drones to attack helicopters and such is incorrect. The difference between being in a helicopter and operating a drone is the cost, one mistake in a helicopter and you could lose your life and your mates life, and also firing on civilians would have a direct impact on you and the way you operate, because you have to go back to your base away from civilisation, and your family. Pressing a button on a control pad in some military base back home would reduce the psychological cost, but that isn't a good thing. Isn't making the individual empathise with the situation important, and not trying to disconnect the operator from the warzone so that killing becomes just another activity.
One good thing though is that people don't have to put their lives on the line in order to perform reconnaissance or simple hit and run missions. Less lives lost = good, but there are other issues that are somewhat important aswell.
