Ultimately, the rules are set by people. I don't see how a machine executing arbitrary rules set by people is that different from people executing arbitrary orders given by people. Just a week ago, two Belgian fighters allegedly bombed a civilian target in Syria, killing four and and further injuring two innocent people. That's a very arbitrary action to take, yet somebody must've ordered the pilots to do that. Perhaps somebody expected there to be armed terrorists there? If they had sent an autonomous robot, with the rules and training to target actually armed targets (how would a robot tell they're terrorists though?), perhaps these civilians would still be fine.
