The crimes are not equivalent, but the "I was just following orders" excuse is just as bogus in both cases.
If you believe that people are responsible for their actions, and they have a choice of what to do, then just because someone gives them an order doesn't mean they have to follow it. They could refuse. If they accept they are then responsible for their own decision and its consequences.
