But we can stop using drones to kill people, we choose not to. Instead, we see drones as a measure to lower the operational cost of killing people allowing us to kill people simply because they are there.
And that's the problem, there is always the Western idea that someone far away must absolutely be killed. And magically, when that person is killed, someone else pops up in their place who needs to be killed even more than the first guy.
It's efficient collateral reducing killing of people who "need to be killed" when it's the West doing it, but uncivilized brutish terrorism when the Other does it.
