Those who give unjustifiable orders or requests are guilty of fraud. Those who kill in obedience to those orders are guilty of murder, or arguably of manslaughter in some cases.

By ordering another person's death unjustly, the order giver makes an invalid claim of ownership over that life and the right to end it. By following the order without due diligence to verify the claim, the order follower demonstrates negligence and a reckless disregard for human life.
